REGRESSION(309544@main): Elements with aspect-ratio don't shrink inside
display flex
https://bugs.webkit.org/show_bug.cgi?id=325275
<rdar://problem/188393652>
Reviewed by Sammy Gill.
309544@main made the flex container invalidate and recompute its items'
intrinsic widths while measuring them.
In a column flex container the item still has the main-axis (height) overriding
size from the previous layout,
and with aspect-ratio that stale height turns into the old width, so the
container (and the grid track it sits in) never shrinks.
