(Core :: Layout, defect, P3)

Description

[Karl Dubost💡 :karlcow]

spin-off of https://webcompat.com/issues/17605


1. Go to http://penang-hokkien.gitlab.io/
2. Just look at the button.

* Firefox and Safari at first load display an oval on the side.
* Chrome gets it right at first load.
* Firefox gets it right if resizing the window (repaint)
* Safari never changes.

That looks like an issue with first painting for the Gecko part.

[Emilio Cobos Álvarez (:emilio)]

Looks a case where incremental reflow disagrees with non-incremental reflow, so moving out of Web Painting.

Sounds like we are not doing something wrong with vertical writing mode.

I mean, we are doing something wrong.

So the root of the testcase seems to be "a thing that's orthogonal inside of an inline-block makes the inline-block the wrong size".

Oh, and the basic reason for the problem is that GetMinISize and GetPrefISize are returning 0 for the div.

This is because we're hitting:
https://searchfox.org/mozilla-central/rev/28daa2806c89684b3dfa4f0b551db1d099dda7c2/layout/base/nsLayoutUtils.cpp#5335-5342

(I don't think we should try to fix this until https://github.com/w3c/csswg-drafts/issues/2890 is fixed in the spec.)

The severity field for this bug is relatively low, S3. However, the bug has 3 duplicates.
:dholbert, could you consider increasing the bug severity?

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.

This is essentially the same thing discussed in bug 1310551. Duping.
