Reported bug on Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=1491235) as one of their tests fail if we remove current behavior regarding size containment and baseline alignment.
That's why the patch marks as failure the test:

[css-contain] Layout and size containment and baseline alignment

The CSSWG has recently resolved that layout containment
suppress baseline alignment, while size containment does not:
https://github.com/w3c/csswg-drafts/issues/2995

Spec text (https://drafts.csswg.org/css-contain/#containment-layout):
  "7. For the purpose of the vertical-align property,
   or any other property whose effects need to relate
   the position of the containing element's baseline
   to something other than its descendants,
   the containing element is treated as having no baseline."

And a note in (https://drafts.csswg.org/css-contain/#containment-size):
  "Note: size containment does not suppress baseline alignment.
   See layout containment for that."

The patch is just a modification in the condition at
LayoutBlock::UseLogicalBottomMarginEdgeForInlineBlockBaseline().

Some tests in the suite need minor modifications
due to the behavior change in order to match the references.

One of the Mozilla tests is failing now, a bug was reported
to get it updated (https://bugzilla.mozilla.org/1491235).

[css-contain] Layout|Size containment and baseline in flexbox|grid

In r591642 we updated the behavior so layout containment
suppress baseline alignment, while size containment does not.
However, we forgot about the special cases (flexbox and grid)
that have their own code for this, which are fixed in this patch.

Regarding WPT tests, these changes will fix the following issue:
https://github.com/web-platform-tests/wpt/issues/13252

One of the Mozilla tests is failing now, it was mentioned
in the associated bug report (https://bugzilla.mozilla.org/1491235).
