      Description

      When a mouse is moved with pressed LMB and then released, there is an unexpected position change event with incorrect mouse coordinates:

      qml: onPositionChanged y:285
      qml: onPositionChanged y:290
      qml: onPositionChanged y:292
      qml: onPositionChanged y:294
      qml: onReleased y:294
      qml: onPositionChanged y:39
      

      To reproduce:
      1) Run the example.
      2) Hover cursor over the red rectangle center.
      3) Press left mouse button.
      4) Move the cursor down out of the rectangle and release the button.

      It shows "onReleased" and then the unexpected "onPositionChanged" with incorrect coordinates.
      The bug is reproducible only one time, then the program has to be restarted to reproduce it again.
