Updated the mouse release event handler to check for the middle mouse button specifically when toggling pan mode, ensuring correct behavior when releasing the middle mouse button.
A comment was added to explain that pan mode is toggled only when not connecting a port and when panning with the middle mouse button. This improves code readability and maintainability.
