Description Richard Pike 2017-11-28 17:12:18 UTC
+++ This bug was initially created as a clone of Bug #39768 +++

When panning, sometimes the PanGestureRecognizer won't reach its completed state when dragging very slowly. This is noticeable on at least Android

Project to use, for ease: https://developer.xamarin.com/samples/xamarin-forms/WorkingWithGestures/PanGesture/

To Reproduce:
Add debug logs or breakpoints at the Gesture.Completed case in the PanContainer.cs's OnPanUpdated method.
When running the application, start a pan, hold it for a moment or two, and release.

Expected behavior:
The completed state is reached.

Resulting behavior:
Occasionally/frequently, this state is not reached.
