In this case, WebKit should display a green rectangle, but it does not display anything. 737674 1 abucur 2012-10-09 04:55:11 -0700 There's a topic on www-style about 0 height regions: http://lists.w3.org/Archives/Public/www-style/2012Sep/0137.html The special case of the last region could contribute to that discussion. 908387 2 mibalan 2013-07-15 06:26:01 -0700 The interesting thing here is that the content does not get displayed only if the region doesn't have a border/padding. As soon as the region has border or padding, the contents are correctly rendered. 908390 3 abucur 2013-07-15 06:48:48 -0700 This is probably another overflow related issue. Because the content is not a child of the region, it assumes there is nothing to paint so it skips the whole thing. 992391 4 227256 mihnea 2014-03-19 23:01:35 -0700 Created attachment 227256 Patch 992406 5 227256 abucur 2014-03-19 23:42:25 -0700 Comment on attachment 227256 Patch r=me 992416 6 227256 commit-queue 2014-03-20 00:14:43 -0700 Comment on attachment 227256 Patch Clearing flags on attachment: 227256 Committed r165951: <http://trac.webkit.org/changeset/165951> 992417 7 commit-queue 2014-03-20 00:14:48 -0700 All reviewed patches have been landed.
