Description Tadeu Zagallo 2018-05-15 13:43:41 PDT 
Follow up from https://bugs.webkit.org/show_bug.cgi?id=184250: initially, the dynamically added event listeners would always be treated as passive. The patch fixes this behaviour, but the first 1 or 2 events still won't be cancellable (unless you touch the DOM). Fixing this should allow for removing the workaround in the previous bug's regression test.

When is this likely to be fixed?

Any idea when this is likely to be fixed? This is quite a serious issue that makes any drag and drop functionality on a reasonably complex website to be very broken. It makes both website owners, library owners, and safari look bad.

Almost everyone affected by https://bugs.webkit.org/show_bug.cgi?id=184250 is still having problems because of this bug. If 184250 was P2 Critical then this should be as well.

Mass move bugs into the DOM component.
