Created attachment 461564 [details] Testcase It seems like we disagree on the Flexbox computed width in certain cases. 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
