What is the current behavior?

When an android view has both single and double tap gesture observers, it emits the tap event delay to leave a small time window for a possible double tap.
Unfortunately, the gesture emits the MotionEvent instance with a delay resulting in incorrect data (e.g. android event system resets the motion to event screen coordinates when done).

What is the new behavior?

These changes make sure that a copy of the motion event is kept before the timer.
The timer will emit the copy, hence the event data at the moment of the actual tap.
The PR also includes small changes regarding setTimeout.
