95453 2012-08-30 06:50:36 -0700 [CSS Regions] Add test for event firing sequence for regionoversetchange with nested namedflows 2022-07-12 17:15:34 -0700 1 1 1 Unclassified WebKit CSS 528+ (Nightly build) Unspecified Unspecified RESOLVED WONTFIX P2 Normal --- 57312 1 mibalan webkit-unassigned abucur bfulgham donggwan.kim stearns WebkitBugTracker oldest_to_newest 708573 0 mibalan 2012-08-30 06:50:36 -0700 The CSS Regions spec currently states that "If region chain nesting occurs (the contents of a NamedFlow contains regions for a different NamedFlow) then the regionLayoutUpdate event for the nested flow(s) must be dispatched before the regionLayoutUpdate event for the containing flow is dispatched." However, in the current implementation, first the event for the containing flow is dispatched and then the event for the nested flow. 708579 1 161460 mibalan 2012-08-30 06:55:36 -0700 Created attachment 161460 Ref test highlighting the problem 709684 2 161711 mibalan 2012-08-31 09:04:22 -0700 Created attachment 161711 Ref test highlighting the problem Uploaded new version that doesn't throw JavaScript exceptions in expected file. 892926 3 stearns 2013-05-23 09:47:01 -0700 The spec has changed to trigger the events at the end of the visual formatting steps, which run outside-in: http://dev.w3.org/csswg/css-regions/#named-flows-layout So the order is correct at this time. We should add a test for this. 900373 4 michelangelo 2013-06-13 20:25:27 -0700 Still repros on today's nightly (r151543) 908684 5 mibalan 2013-07-15 22:48:05 -0700 Since the spec doesn't make any specification of event timing for nested regions, this should be closed as soon as we remove the regionlayoutupdate event. 908878 6 stearns 2013-07-16 07:16:12 -0700 The spec does say how events in nested regions should trigger. The implementation matches the spec at the moment. 1882796 7 bfulgham 2022-07-12 17:15:34 -0700 CSS Regions were removed in Bug 174978. 161460 2012-08-30 06:55:36 -0700 2012-08-31 09:04:22 -0700 Ref
