Only the WebKit browsers return 0, the other browsers FF/IE/Opera return auto. Since region elements do not have children and paint the flow thread content, i resorted to this test since we already have tests for regions as stacking contexts with siblings. 937021 3 mihnea 2013-10-07 04:44:30 -0700 An old (related) WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=15562 about computed zIndex. 937567 4 213496 abucur 2013-10-08 10:07:18 -0700 Comment on attachment 213496 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=213496&action=review > Source/WebCore/rendering/style/RenderStyle.h:892 > + bool hasStyleRegion() const { return !rareNonInheritedData->m_regionThread.isNull(); } Would "isNamedFlowRegion" be more precise? 937570 5 213496 hyatt 2013-10-08 10:09:47 -0700 Comment on attachment 213496 Patch r=me, 937585 6 213496 commit-queue 2013-10-08 10:32:18 -0700 Comment on attachment 213496 Patch Clearing flags on attachment: 213496 Committed r157121: <http://trac.webkit.org/changeset/157121> 937586 7 commit-queue 2013-10-08 10:32:20 -0700 All reviewed patches have been landed.
