I've uploaded a gif to try and demonstrate the problem, you can view it here (80mb):
My "map" is in a horizontal scrollview with a drag component. When I drag from the left side it works fine but when I drag the the right side at the end of the scrollview it automatically snaps back to the end even though I am still dragging it.
I am on v 3.6.7. I have not updated to the very latest release because the removal of the BetterList and various issues that means my UI doesnt work like it did.
