Summary Safari on iOS fires "pointerenter" with mouse pointerType in addition to touch

When you have an element with a `tabIndex`, Safari on iOS fires the "pointer enter" and "pointerleave" events twice: once with `pointerType` set to "touch", and again with `pointerType` set to "mouse". After touching and releasing the element, the events fired are: * pointer enter: pointerType = "touch" * pointer leave: pointerType = "touch" * pointer enter: pointerType = "mouse" A pointer leave event with pointerType = "mouse" is not fired until the element is blurred (e.g. by tapping on something else that's focusable). Based on this information, it appears that focus/blur events are also causing pointer enter/pointer leave events. You can try this out in a demo here: https://codepen.io/devongovett/pen/QWyYWYa

> * pointer enter: pointerType = "touch" > * pointer leave: pointerType = "touch" > * pointer enter: pointerType = "mouse" These seem like events that would be fired when dispatching synthetic click events, which should be fixed in the iOS 14 beta.

I am unable to reproduce this bug using iOS 15.6.1 on iPhone 13 Pro Max and it does not show ‘mouse’ with positionenter in the demo from Comment 0. @Devon - if it is reproducible, appreciate if you can share updated testcase. Thanks!

I can confirm that it appears to be fixed in the latest iOS version.
