Hi all,

I just compiled an implementation report for CSS-CONTAIN-1, and things are looking pretty good.

If we discount tests for the at-risk feature (contain:style) and cross-spec tests that involve other specs not yet at PR (ruby and grid), all but 2 tests in the test suite pass in both Chrome and Firefox.

The two that don't are depending on a very minor known bug in Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=1562057): when contain:size is applied to <select> elements, Firefox correctly makes their size no longer depend on the content, but gets the size of the empty <select> slightly wrong (by the width of one &nbsp;).

Other than that, it's all good.

To be honest, I think that Firefox bug is so small that we should be able to go to PR even before it gets fixed, but it would be even nicer to actually fix it.
