The underlying issue is described here: https://bugzilla.mozilla.org/show_bug.cgi?id=1030952#c2 I believe the tentative patch there works, but it's not sufficient to entirely fix the bug, as discussed in https://bugzilla.mozilla.org/show_bug.cgi?id=1030952#c9 Possible workaround for the moment: wrap your <img> in a wrapper-block with 'min-width:0', and force the img (now a child of a block) to be "display:block" itself as well: https://jsfiddle.net/dfpj6fag/7/ ~Daniel On 01/28/2016 04:52 AM, Amit Zur wrote: > I'm seeing an aberration in behaviour of img as a flex-item. > Not sure what is the reason, but the img doesn't preserve aspect ratio, as > seen in this fiddle: > https://jsfiddle.net/dfpj6fag/6/ > > I saw this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=972595 but I > can't understand if it's related or what is the exact reason the ratio is not > maintained. > > Thanks, > Amit > _______________________________________________ > dev-platform mailing list > dev-platform@lists.mozilla.org > https://lists.mozilla.org/listinfo/dev-platform > _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
