This needs to be corrected. 1075686 1 webkit-bug-importer 2015-03-09 11:49:44 -0700 <rdar://problem/20093511> 1075701 2 bfulgham 2015-03-09 12:09:42 -0700 The problem is that we trigger the animation on the "scroll end" phase, which we never receive for mechanical wheels. This is similar to the difficulty in scroll latching. We may need to create some kind of wheel event metric that trigger the animation event if a sufficient amount of time passes from the last wheel event. 1105329 3 255734 wenson_hsieh 2015-06-28 18:04:55 -0700 Created attachment 255734 Patch 1105919 4 255734 bfulgham 2015-06-30 18:01:26 -0700 Comment on attachment 255734 Patch I think this looks good. r=me. 1105926 5 255734 commit-queue 2015-06-30 18:52:13 -0700 Comment on attachment 255734 Patch Clearing flags on attachment: 255734 Committed r186160: <http://trac.webkit.org/changeset/186160> 1105927 6 commit-queue 2015-06-30 18:52:16 -0700 All reviewed patches have been landed.
