How to reproduce

Safari on iOS 13.4.1 open bug_reproducer.html

1. finger touch (touchstart fired)
2. finger remove (touchend fired)
3. - execute next steps immediately like by double click -
4. finger touch (NO touchstart fired)
5. finger MOVE (NO touchmove fired)
6. finger remove (NO touchend fired)
In this scenario 4-6. steps are not anymore fired.

Same way Android Chrome fires 4.-6. steps correctly, and even more double touch increases on Android Chrome amount of fired touchstart/touchend events always by 2 event sequences(2start and 2end) as expected. But iOS 13.4.1 Safari fires always only one event sequence (1start and 1end).
This is serious bug in detection of "double touch move" gesture in our application.
