[Webkit-unassigned] [Bug 191218] Touch event not firing while scrolling is in motion

--- Comment #2 from Frédéric Wang (:fredw) <fred.wang at free.fr> ---
Preliminary debugging on the simulator (public SDK):

- When you scroll and tap the blue rectangle during scrolling, WKScrollingNodeScrollViewDelegate::scrollViewDidEndDragging is called and just informs ScrollingTreeScrollingNodeDelegateIOS about the scroll & scroll end.

- When you tap directly the blue rectangle, WKContentView::_singleTapGestureRecognizer will invoke WebPageProxy::commitPotentialTap in order to tell the Web process to dispatch an event.

- WKContentViewInteraction::gestureRecognizerShouldBegin has some logic when tap interrupts a scroll deceleration, but the code does not seem to be called for me.

I wonder if there is something wrong in the fact that touch gesture are not handled by WKContentView during scrolling or if the scrolling delegate should do similar work as WKContentView to recognize touch gestures.
