It also opts out of click events. Example: https://codesandbox.io/s/touch-events-fspff My understanding is that this is not correct. I would think that `event.preventDefault()` on a `touchforcechange` event should only prevent the default forcechange action from occurring, and not other actions 1551604 1 alexreardon 2019-07-09 23:00:47 -0700 I do not have access to an old device right now, but I think this might be a recent change 1551608 2 alexreardon 2019-07-09 23:29:24 -0700 Whoops - I meant old OS version 1551676 3 webkit-bug-importer 2019-07-10 09:08:48 -0700 <rdar://problem/52894746> 1552384 4 graouts 2019-07-12 02:45:36 -0700 Hi Alex.
