"Mouse Lock" ignores very slow Mouse Movements

[PrimaryFeather]

Problem Description

When enabling mouse lock, Flash's mouse events do not process small movements any longer.

• Tested with AIR 27 on macOS and Windows
• Also tested with Flash Player 27

Adobe Tracker Issue: AIR-4198463

Steps to Reproduce

• Run the sample code from this Gist in a Flash Player or AIR application.
• Hit "F" to change to fullscreen mode.
• Note that the red circle follows the mouse position, even when you move the mouse only very slowly.
• Now hit "M" to activate mouse lock.
• Now, when moving the mouse very slowly, the circle won't move any more.

I'd expect the accuracy of the movement to be exactly the same, whether mouseLock is on or off.

Thanks for taking the time out to test my demo and reproduce the issue in 'classic' display, Daniel!
I'm glad I wasn't wrong about the way the mouse behaves whilst making use of mouseLock. 😄
