Updated image with placeholder of similar size in JSFiddle - https://jsfiddle.net/qtzmng5h/ Safari 17.6 Beta & Chrome Canary 128 are matching while Firefox Nightly 129 is different.

This is the comment on the bugzilla bug > This is expected result of Mozilla 1585485 [3], which implements [1]. The percentage width: 100% on the image flex item (which is compressible [2]) makes the min-width:auto resolved against 0. The item also has flex-grow:0 preventing it from being stretched, so the final resolved width is the flex-basis:20%, which is 80px. > > I add another testcase that has <input> added as an flex item. Both <input> and the image should have the same width. > > [1] https://drafts.csswg.org/css-sizing-3/#replaced-percentage-min-contribution > [2] https://drafts.csswg.org/css-sizing-3/#min-content-zero > [3] https://bugzilla.mozilla.org/show_bug.cgi?id=1585485
