You can check this demo: https://cdpn.io/wss534857356/debug/yLOLgQZ/xnkabZPBDDvM. You can use the iOS14 to open this demo. When you click the next button twice, you will find that it cannot be overworked normally. 1678345 1 webkit-bug-importer 2020-08-06 12:04:38 -0700 <rdar://problem/66638568> 1678739 2 jonlee 2020-08-07 14:27:09 -0700 Is this a regression from a previous version of iOS? 1682323 3 graouts 2020-08-24 07:54:47 -0700 The original link does not work but I think this is the reported example: https://codepen.io/wss534857356/pen/yLOLgQZ This shows different behavior between iOS 13.6 and an iOS 14 beta. I can see the iOS 14 beta change in STP 112 but not a ToT Safari build, so this may be a regression that was addressed recently. 1682334 4 graouts 2020-08-24 08:13:25 -0700 Duplicate of bug 215655. *** This bug has been marked as a duplicate of bug 215655 ***
