Bug 232987 – [css-grid] Transfer size for grid item with an aspect-ratio and stretch alignment against the definite row

• Component: CSS
• Status: RESOLVED FIXED

This is similar to bug 231802. Instead of having a percentage of the definite row, the grid item stretches in the block-axis.

I think a comment here, explaining why we need to apply the stretch alignment, and how it affects the aspect-ratio, would be a good idea.

Do we need to check for isGridItem() ? wouldn't this be relevant for flexbox (the other layout model applying stretch alignment) as well ?

Yes, I think we do need to check for isGridItem(). I have seen a couple of table related tests failures without this check. Tried running WPT flexbox tests with the check (e.g. add (isGridItem() || isFlexItem()) but couldn't see it makes any difference on the test result for flexibox tests.
