When I run open the test page in a debug build, it asserts with "HasAnyStateBits(NS_FRAME_OUT_OF_FLOW)" inside GetPlaceholderFrame(), so this is a first-letter frame which has float but doesn't have NS_FRAME_OUT_OF_FLOW bit set, which sounds wrong.

Yeah, and this is because we try to reparent an in-flow first-letter frame style, and it ends up inheriting the float value from our parent due to the all: inherit rule.

Now, changing from float: none to float: left on the parent should've reframed it...

So, this is because when creating the first-letter frame, we end up unconditionally inheriting from the first-line (non-floated), not from the block (which is floated).

When we reparent the style context we (correctly) use newParentIgnoringFirstLine.

So I think we need to move that logic to the "create a first-letter" bit.

Boris, maybe you could review this?

See the commit message, I think this is the less disruptive patch (and a first-letter inheriting from a first-line is already uncommon).

But let me know if you want me to pass the parent style ignoring first-line around instead or what not.

Review of attachment 8906511 [details] [diff] [review]:
-----------------------------------------------------------------

I think this is OK.  It is kind of unfortunate that we need to go through a ReparentStyleContext rather than some other function that can give us a correctly inherited style context to begin with, but it's probably not a big deal.

So, cam mentioned that we were not doing the same in nsBlockFrame::UpdateFirstLetterStyle. I think it's correct because of the reparenting we do when updating first-line styles afterwards.

However, the fact that we compute change hints for it means that we'll compute the change hint with the floating style, and thus reframe unnecessarily. I think it's not a huge deal though, maybe worth filing a followup after this lands.

Emilio, thank you for picking this up!

I have two nits about the patch:

1)  I believe the block at http://searchfox.org/mozilla-central/rev/00fa5dacedb925022f53d025121f1a919508e7ce/layout/base/nsCSSFrameConstructor.cpp#12259-12270 can go away now.

2)  The aNewLayoutParent to ReparentStyleContext should be parentStyleContext->AsServo(), not parentStyleIgnoringFirstLine.  I use "should" in the loosest possible sense, because the interaction of all this stuff with display:contents in the spec is at best "unspecified".
