Somewhat close to the description of this bug are: Bug 478834: table following left float doesn't clear it even if it can't fit next to it (& same for block-level img, flex container, etc. following left float) Bug 14984: [FLOAT] Tables overlap right floats (e.g., right-aligned images or tables) so this could still be a DUPLICATE of one of those...

Another consequence of this bug: the horizontal contiguous margins - which should not collapse - between 2 floated contiguous tables are substracted by the total of table borders and table (or cell) padding separating them. In this test http://test.csswg.org/source/css-writing-modes-3/table-progression-vrl-004.html the gap between tables should be 32px (or 2em) but it is 24px (32 - (2 * 3) - (2 * 1)). - - - - - - - Additional tests: Both tables have 25px borders between them http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/contiguous-floated-table-vrl-006.xht Both tables have 25px padding between them http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/contiguous-floated-table-vrl-008.xht Firefox 45.0a1 buildID=20151128060058 fails both tests. IE11, Edge 12 and Chrome 48.0.2564.10 pass both tests.

Firefox 46.0a1 buildID=20151219081206 fails http://test.csswg.org/source/css-writing-modes-3/table-progression-srl-002.html http://test.csswg.org/source/css-writing-modes-3/table-progression-slr-002.html http://test.csswg.org/source/css-writing-modes-3/table-progression-vrl-002.html http://test.csswg.org/source/css-writing-modes-3/table-progression-vlr-002.html because of this bug, because of how shrink-to-fit applies to floating boxes (that have borders) in orthogonal context. This bug is somehow related (a sibling of) to bug 1166120 . Chances are that, when bug 1166120 gets fixed, then this bug could be fixed; so, at that time, this bug report should be revisited.
