Here's the frame tree we create for this testcase:
Block(body)
Ruby(ruby)
RubyBaseContainer(ruby)
RubyBase(ruby)
Inline(span)
Block(span)
nsTextControlFrame ...
Inline(span)
where "Block(span)" is "aFrame" in the assertion condition.
At first glance, this seems like an invalid frame tree because
children of RubyBase should have been Inlinified, per step 1 in:
https://drafts.csswg.org/css-ruby-1/#box-fixup
BTW, the frames for <span> above is an ib-split sequence.|

So the problem is that inlinification of layout-internal display values map to themselves so adjust_for_ruby() doesn't do anything. Then, since it's a <textarea>, we can't create table pseudos either, so we end up with a nsTextControlFrame with a 'table-header-group' inside an inline, which triggers the ib-split which wraps it in a ::-moz-block-inside-inline-wrapper which has 'display:block' which is invalid inside <rb>. A solution which I think could work is to simply use an anonymous wrapper that has 'display:inline-block' instead.

So (just double-checking here, so feel free to ignore), the issue is that a frame for a textarea (or any other frame that we don't honor display for really) with a table-internal display type is, effectively: IsBlockOutside() -> false IsInlineOutside() -> false StyleDisplay()->IsInnerTableStyle() -> true Yet it of course doesn't create any table wrappers, since it's not a table frame. It may be worth to inlinify table-internal display types Why do we split frames to find the first block using !IsInlineOutside() instead of IsBlockOutside()? That seems slightly suspicious, but we do it in a bunch of other places, and it looks like Blink and WebKit do the same thing, if I'm reading their code right... (Maybe we don't need to though). It's not clear to me what a table-internal display type on a textarea is even supposed to mean... Oh well. Also, looks like we do something slightly different for <svg:text>: https://searchfox.org/mozilla-central/rev/f997bd6bbfc4773e774fdb6cd010142370d186f9/layout/style/nsStyleStructInlines.h#105 For which we wouldn't end up creating an IB split in this case... Though I suspect you can't do something like stashing an <svg:foreignObject> with a <textarea> inside <svg:text>, can you? If so, it'd be nice to unify both codepaths... Why don't we need to check the new pseudo type in ComputeAndIncludeOutlineArea? https://searchfox.org/mozilla-central/rev/f997bd6bbfc4773e774fdb6cd010142370d186f9/layout/generic/nsFrame.cpp#9838 Maybe a static function like `nsCSSAnonBoxes::IsIBSplitWrapper(nsAtom*)` would make it a bit harder to mess up in the future? Not a big deal though. I'd like bz to sanity-check the approach here when he has the time, though feel free block landing this in the meantime, it's not a very invasive / complex patch anyway, and it seems consistent with what bug 1021952 introduced for tables.

Can we just do blockFrame->Style()->GetPseudo()? The SetComputedStyle call will assert if the condition is wrong anyway, but it seems worth to avoid duplicating the logic here.

I think you should check `aInitialInline->Style()->ShouldSuppressLineBreak()` instead, so that you don't need to rely on ruby utils, and the code doesn't need to be adjusted in the future if other stuff starts to require the same behavior (although I doubt whether there would be any). ::: layout/generic/nsInlineFrame.cpp @@ +958,5 @@ > > // The anonymous block's style inherits from ours, and we already have our new > // ComputedStyle. > + auto parentType = GetParent()->Type(); > + auto* pseudo = MOZ_UNLIKELY(RubyUtils::IsRubyContentBox(parentType)) ?

I would consider this as an edge case that we don't really need to care much about. Wrapping ib-split parts inside an inline-block for inlinified context sounds fine to me if it's the simplest approach. I think it's also fine to inlinify internal display types since why anyone would want to do that...

(In reply to Emilio Cobos Álvarez (:emilio) from comment #4) > Yeah, I agree this looks reasonable, but I'm still somewhat fascinated us > entering the ib-split code in the test-case... Normally, say for <rb><span><div style="display:table-header-group">, when we enter CreateNeededPseudoContainers for the <span>, aItems.AllWantParentType(ourParentType) is false: "ourParentType" is eTypeBlock but the desired type for the <div> is "eTypeTable", which comes from FCDATA_DESIRED_PARENT_TYPE_TO_BITS(eTypeTable) on "FCDATA_FOR_DISPLAY( StyleDisplay::TableColumnGroup". But for <textarea> etc we don't create frames based on 'display' really. We go through FindHTMLData instead. I guess we could add "DESIRED_PARENT_TYPE" bits there based on 'display' but we don't normally (as in non-Ruby) create table pseudos for such elements so I don't think we should introduce that here. e.g. data:text/html,<textarea style="display:table-header-group"> > IsBlockOutside() -> false > IsInlineOutside() -> false > StyleDisplay()->IsInnerTableStyle() -> true Correct. > It may be worth to inlinify table-internal display types There are no inline versions on the table-internal values though. I guess we could make it 'inline-table/block', but that would require spec changes... Then again, that seems to be what Chrome does... (the computed value is 'inline-block' in its devtools panel) and it does this for non-Ruby too, which makes us incompatible for things like: data:text/html,<span>A<input style="display:table-header-group">B It only does that for some (replaced?) elements though, data:text/html,<span>A<div style="display:table-header-group"></div>B computes to 'table-header-group'. Yikes... (Fwiw, Edge seems to follow the specs) > Why do we split frames to find the first block using !IsInlineOutside() > instead of IsBlockOutside()? I don't know.

So historically we used IsInlineOutside() here to make sure that anything inside an inline was really ok to have inside an inline. I think it would be ok to switch to treating table-internal display types as consistently not inducing ib splits. Per spec, this is how it should work, since per spec they should get wrapped in anon boxes ending up with an inline-table. We (and everyone else) just doesn't do that for replaced elements. In Blink and WebKit some replaced elements (e.g. input, textarea) effectively do this by forcing display to inline-block if it's table-internal. But others (e.g. img) don't do that and end up inducing ib splits...

I'm not sure if we should change mIsAllInline.
It seems it's more for the definitely-inline-outside case:
// Whether construction from this item will create only frames that are
// IsInlineOutside() in the principal child list. This is not precise, but
// conservative: if true the frames will really be inline, whereas if false
// they might still all be inline.
bool mIsAllInline:1;
I haven't looked in detail how it's used though...|

I expect the only use of mIsAllInline is for ib split stuff.

I double-checked and the only types that are neither IsInlineOutside nor IsBlockOutside nor internal table parts are xul display types. Given those are not web-exposed nowadays I think this change is not really risky.
