Actual results for Unprefixed tests
-----------------------------------

There is an incomplete layout of the table-cell: the background color and the border are not painted. Only the left border is painted. I can load a screenshot if requested.

Notes
-----

- Firefox 45.0a1 buildID=20151124030553 fails the line-box-direction-015 and 016 tests
- I have "Enable multi-process Nightly" checkbox UNchecked; I have not verified yet if checking it also gives me actual results
- when toggling off and on the border declaration with Inspect Element/Inspector Tool, the layout issue is solved: this is what makes me think there is final layout or painting failure somewhere in the code
- what I do not understand is why wm-line-box-direction-011 and wm-line-box-direction-012 are passed when they are basically and fundamentally the same tests ... when the only difference is font fetching
- I use Linux 3.13.0-68-generic x86_64, Qt: 4.8.6, KDE 4.13.3; Kubuntu (utopic) 14.04.3 LTS
- I've searched for duplicates and did not find any.

I do not know if this issue is reproduced under Windows and Mac. So, I only the OS field is Linux for now.

Comment 2

[Gérard Talbot]

With "Enable multi-process Nightly" checkbox checked in Firefox 45.0a1 buildID=20151124030553, the issue is the same: I still get actual results.

With "Enable multi-process Nightly" checkbox checked, wm-line-box-direction-011 and wm-line-box-direction-012 tests now fail as the table-cell borders and background-color are incompletely rendered.

Unfortunately, we recently had to filename-rename many tests and this affected the tests mentioned in comment 0.

Here are the current links to tests:

Firefox 45 (final release) buildID=20160304114926 now passes

http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/orthogonal-vrl-table-cells-002.html

but those 7 tests fail in Firefox 47.0a1 buildID=20160304163750. Again, those 7 tests *would pass* in Firefox 47.0a1 buildID=20160304163750 when/after toggling on and off the border declaration with Inspect Element/Inspector Tool, suggesting a reflow missing somewhere...

(...)

Firefox 45 (final release) buildID=20160304114926 and Firefox 48.0a1 buildID=20160406030221 all fail these 7 tests. The previous comment, except for the toggling on and off of the border declaration, is incorrect.
