This may have been a regression from r222392. To reproduce: 1. Open https://codepen.io/cdumez/pen/xjEmdX in MobileSafari 2. Tap the red box and notice that the touchstart / touchend event timestamps are positive. 3. Put MobileSafari in the background for ~5 minutes then re-open MobileSafari 4. Tap the red box again and notice that the touchstart / touchend event timestamps are now negative :( 1418195 1 cdumez 2018-04-26 12:42:02 -0700 <rdar://problem/39638051> 1418510 2 cdumez 2018-04-27 09:40:14 -0700 The actual fix is in UIKit when generating the touch's timestamp. I will use this bug to do some hardening in WebKit to make sure Event.timestamp can never return a negative value. 1418547 3 339005 cdumez 2018-04-27 10:52:50 -0700 Created attachment 339005 Patch 1418622 4 339005 commit-queue 2018-04-27 14:21:35 -0700 Comment on attachment 339005 Patch Clearing flags on attachment: 339005 Committed r231111: <https://trac.webkit.org/changeset/231111> 1418623 5 commit-queue 2018-04-27 14:21:37 -0700 All reviewed patches have been landed.
