Rectangle selection marquee can stay stuck if exiting the timeline canvas boundaries during drag

Description
Insert a clip in the timeline, click and drag from any empty part of the timeline to initiate a rectangular selection. Keep dragging until your mouse cursor reaches the ruler or above.
Result: the selection marquee stays "stuck" until you click in the timeline again.
This does not happen if your "exit zone" is on the left, right or bottom of the timeline, only on the top side.
