In the example I am using, we compute a width of 180. I think this is from 100px (content) + 80 px (border and padding being added twice to the child which is another bug). Both Firefox and Chrome compute a container size of 65px (the border box size of the child). So it seems like there are 2 possible issues here: 1.) We are incorrectly computing an initial content size of 100px (Unless this is correct and both Firefox/Chrome are wrong) 2.) Incorrectly adding border+padding twice to child width 1890938 1 webkit-bug-importer 2022-08-12 10:55:15 -0700 <rdar://problem/98577125> 1892038 2 sgill26 2022-08-17 13:56:54 -0700 Pull request: https://github.com/WebKit/WebKit/pull/3423 1896522 3 ews-feeder 2022-09-06 10:23:48 -0700 Committed 254190@main (0599c10f9004): <https://commits.webkit.org/254190@main> Reviewed commits have been landed.
