Created attachment 360977 [details] testcase Open the attached testcase. The margin should be outside the box due to margin collapse. This happens when the container has height:100%, but doesn't when it's height:auto. Per spec, it doesn't make sense. This is filed as a webcompat issue to Firefox, see https://bugzilla.mozilla.org/show_bug.cgi?id=1524656 I have also filed a bug to Blink: https://bugs.chromium.org/p/chromium/issues/detail?id=928027

We match Chrome behavior in macOS 13 (and probably previous to that).
