Bug 140543

Created attachment 244760 [details] Example to reproduce the issue First bug #140541 should be fixed, but this issue was present before and it's still present in Blink (https://code.google.com/p/chromium/issues/detail?id=449481). Example (attached) to reproduce the issue ("Green" should be green and "Black" should be black): <style> .first-line-green::first-line { color: lime; } .flex { display: flex; } </style> <div class="first-line-green"> <div class="flex"> Black </div> Green </div> The flex is ignored as expected, however it doesn't go to the next element (like in the case of floated/positioned elements). BTW, the same happens for grids. From the spec (http://www.w3.org/TR/css-flexbox-1/#flex-containers): "the ::first-line and ::first-letter pseudo-elements do not apply to flex containers, and flex containers do not contribute a first formatted line or first letter to their ancestors." Also a mail from CSS WG mailing list confirming the expected behavior: http://lists.w3.org/Archives/Public/www-style/2014Dec/0305.html
