fix: Limit calculation bug when dragging and resizing

[lihuaabcder]

Hi,

Phenomenon: When both left and right mouse buttons are pressed simultaneously to drag or resize, the component becomes "stuck" and can only be restored by refreshing the page.

Cause: When the left mouse button is clicked, it indicates dragging or resizing. If the right mouse button is accidentally pressed at this time, the mousedown event triggers the ”deselect“ function and resets the mouse state in the DOM. This can lead to incorrect internal calculations resulting in NaN.

Solution: Both drag and resize events share a common feature of triggering a mouse click event. A local variable can be created as a "lock." This "lock" is then released after the mouseup event occurs.
