  1. with Firefox Fenix on Android
  2. open https://pages.lazada.co.id/wow/i/id/LandingPage/flashsale?spm=a2o4j.home.flashSale.1.579978386G7IZc

EXPECTED:
the website is displayed

ACTUAL:
The site is blank.

See https://webcompat.com/issues/40379 for the remedy

I created a reduced test case where this is happening.
This markup is working on desktop, but fails on mobile. The html, body and div have a 0 height only on mobile.

data:text/html,<!DOCTYPE html><html lang="id"><head><meta charset="UTF-8"><style>html, body, .flash-sale { display: flex; position: absolute; }</style></head><body><div class="flash-sale">foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar    foobar</div></body></html>
Summary: can't open the page. Just blank → body height is 0 with display:flex on mobile.

In the reduced testcase, the html and body elements should have zero height since they contain only abs.pos. children.
Is that div's height really zero on mobile? That's clearly a bug if so.
(I'd be surprised if that's the case though since the layout sizing code should have the same behavior for desktop/mobile on all platforms.)

Does the testcase display differently in Chrome on Android compared to Fenix in any way? If so, how?
(Fwiw, html and body have zero height in desktop Chrome.)

Flags: needinfo?(kdubost)

I can scroll the attached testcase just fine in Fenix and Fennec, FWIW. I don't see any differences between Firefox and Chrome on that testcase right away.

I do see an issue at the original page, though: the live "flashsale" URL renders as a mostly-blank page (with just a single line of text <- Flash sale: Diskon Terbesar ...), in all configurations I've tested (Fenix, Firefox desktop RDM, Chrome-for-Android, and Chrome-RDM). In Chrome, however, the page gets populated with more content after ~1 second, and that seems to happen via content being appended to the DOM. (Specifically, <div class="flash-sale"> gains a new child which contains all of the content.)

That element does get added on Firefox, but it is indeed 0 height for some reason.

Attached file testcase 1 —

The reduced testcase was missing top:0; bottom:0 which is the key thing that you'd expect to make the content not have zero height. (This styling is present in the original external URL and is why the issue shows up there.)

With that change, I can reproduce a difference in behavior in Firefox vs. Chrome (on desktop, and I assume on mobile too). Chrome renders the testcase with a large bordered lime rect, wheres Firefox collapses the rect to 0 height.

Attachment #9097265 - Attachment is obsolete: true

Also, if I adjust the testcase to use display:block instead of display:flex just on the <html> root-element, then I get EXPECTED RESULTS.

So this is something weird about having that root element be a flex container.

This testcase has nonzero values for the positioning properties. We seem to ignore those properties entirely here.

If I use display:block, we honor them (and match Chrome).

Attachment #9097434 - Attachment description: testcase with nonzero top/right/bottom/left → testcase 3 (with nonzero top/right/bottom/left)

(I see the same bad rendering with display:grid, too, BTW. So there must be some special case that we've got implemented for block that we need to extend to handle these other containers as well.)

Summary: body height is 0 with display:flex on mobile. → abspos root element (html) ignores top/right/bottom/left properties, if it has "display:flex" or "display:grid"

Triaging as P3 and unsetting per-version affected flags, because this seems to not be a regression (it affects builds at least as far back as 2015-01-01 and probably indefinitely far back).

From the frame tree dump below, it seems a position:absolute flex or grid root element is not setup properly as an out-of-flow frame and it remains in the principal child list. The block frame in the the reference case is the correct.

Partial frame tree of testcase 2 (comment 5)

    Canvas(html)(-1)@7f310f6880c0 parent=7f310f688198
      FlexContainer(html)(-1)@7f310f688a80 parent=7f310f6880c0

Partial frame tree of reference case 2 (comment 6)

    Canvas(html)(-1)@7f310f44d0c0 parent=7f310f44d198 
      Placeholder(html)(-1)@7f310f44db40 parent=7f310f44d0c0

          Block(body)(2)@7f310f44dbc0 parent=7f310f44da80

If contentFrame is out-of-flow, nsFrameConstructorState::AddChild() can
construct a placeholder frame for contentFrame and put the placeholder in
frameList.

Also, we need to use nsFrameConstructorState::GetGeometricParent() to
get the correct parent when calling InitAndRestoreFrame() for an
out-of-flow contentFrame. For example, if contentFrame has
position:fixed, its parent should be ViewportFrame, not
CanvasFrame (which is mDocElementContainingBlock).

This patch also adds reftests for position:absolute flex & grid root
element. Reftests for position:fixed root element are in the next part.

Flags: needinfo?(aethanyc)
Upstream PR was closed without merging

I took a quick peek at the crash since that crashtest is using Grid. I think it's an unrelated crash in Graphics code. When I run the test locally with the patch applied then I see:

[GFX3-]: Surface size too large (exceeds extent limit)!

in the terminal but no crash. I suspect that the OOM on Android is related to that though.

So I think we can disable this crashtest on Android and file a follow-up bug (in Web Painting) on that, and then re-land this fix (which looks correct to me).

Mats, thank you for taking a look at the failure and my patch! I filed bug 1639947 for the OOM crash on Android. I'll disable the test on Android and reland the fix.

OK. So by looking at other autoland runs after mine like this one, the OOM crash can happen not only on Android or Windows, but also on macOS. Thus, I'll add a part 0 to completely disable the test, but I'll copy the test and change the scale to 1, which is sufficient to trigger bug 1608851.

Part 0 - Skip 1608851-1.html since it causes OOM crash on multiple platforms after applying Part 1. r=mats
https://hg.mozilla.org/integration/autoland/rev/19b910256abf
Part 1 - Use nsFrameConstructorState::AddChild() to construct out-of-flow flex or grid container as the root element. r=dholbert
https://hg.mozilla.org/integration/autoland/rev/a00f71376ad1
Part 2 - Add reftests for position:fixed flex & grid root element. r=dholbert
Upstream web-platform-tests status checks passed, PR will merge once commit reaches central.
