The touch sequence: finger touch > finger release > finger touch > finger move > finger release, where last 3 event types get not reported to event handling. On earlier iOS versions like iOS12 the sequence above fired following events: 1. touchstart 2. touchend 3. touchstart (in fast sequence to previous touchend) 4. touchmove 5. touchend (when moving ended) On new iOS 13 versions on tested iPad only first two 1. touchstart 2. touchend 3. ---- not fired> touchstart (in fast sequence to previous touchend) 4. ---- not fired> touchmove 5. ---- not fired> touchend In such case not event dblclick gets fired. Unfortunatelly unreported "dbl-touch and move" breaks functionality of our software. Pointer events have same issue like touch events, they are not propagated to DOM if detected by iOS as potential dblclick even if moved between.
