Hi,
Recreating bug:
- Click and hold down the mouse button (don’t unclick) and start dragging
- While dragging (but before unclicking), move your mouse outside the Gantt container (the task should still move with your mouse)
- Unclick (release the mouse button) while outside the Gantt container
- Go back to the gantt container and move your mouse around. The task you were dragging previously is still being dragged despite releasing the mouse button
Probable cause:
The mouse release listener for the drag event is bound to the Gantt container and not the entire browser window.
This bug also exists in the samples.
