Bug 2000722 [wpt PR 56074] - Add test for column balancing and row wrapping., a=testonly
Automatic update from web-platform-tests
Add test for column balancing and row wrapping.
The spec issue has been resolved:
https://github.com/w3c/csswg-drafts/issues/11976#issuecomment-3530659488
This already matches our behavior. I.e. don't let column rows stretch
the column lines.
