Bug description

No response

Steps to reproduce

1. Start dragging a clip across the timeline
2. Move the cursor outside of Audacity's window
3. Observe

Expected behavior

When the cursor leaves the Audacity window, do one of the following (whichever requires the least dev effort and naturally behaves better):

• Horizontal scrolling stops and the clip is placed at the nearest point where the cursor left the window.
  OR
• The drag operation is cancelled and the clip returns to its original position (this is what Logic, Premiere and others do, so is probably the most sensible solution).

Actual behavior

Horizontal scrolling continues indefinitely. Clicking on the timeline is required to stop it.
