Steps to reproduce the problem: Open WPT test https://wpt.live/css/css-flexbox/item-with-table-with-infinite-max-intrinsic-width.html What is the expected behavior? There should be a 100x100 px green square What went wrong? There is a 63995x50 px rectangle. See: https://wpt.fyi/analyzer?screenshot=sha1%3A6c9fe7047bcdb2d4bd3a476bd32790266513ac46&screenshot=sha1%3A293dade16746f290a817a505afd1b123c1e44c7c Does this work in other browsers? Yes. This issue has been reported and fixed for Chrome in htpps://crbug.com/850566 And the very same issue (but for css-grid) its reported in bug 191365
I'm merging this with 191365. They are not exact duplicates because they affect different layout systems (grid and flex) but the fix is the same for both. *** This bug has been marked as a duplicate of bug 191365 ***
