            Bug ID: 220642
           Summary: Long pressing on an img that has
                    -webkit-touch-callout: none causes an extra mousedown
                    to fire
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org

On an iOS device, long pressing on a regular div fires two events: a touchstart, and then a touchend when the finger is released. Long pressing on an img element, however, fires three events: a touchstart, then a short while thereafter a mousedown, and finally a touchend. I've written up a trivial example to show this difference at https://codepen.io/JarodG/pen/zYKMeaJ

I'd expect that, with -webkit-touch-callout disabled (which prevents the image preview / save callout) the long press behavior would be the same between these two elements, especially since a regular tap fires the same events for both.
