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

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: FAILED tests: http://test.csswg.org/source/css-writing-modes-3/line-box-direction-vrl-015.xht http://test.csswg.org/source/css-writing-modes-3/line-box-direction-vlr-016.xht Others: http://test.csswg.org/source/css-writing-modes-3/line-box-direction-srl-055.xht http://test.csswg.org/source/css-writing-modes-3/line-box-direction-slr-056.xht

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.
