as you can see in the GIF, if you press on the X point and change it to any number (ex: 33) and then try to drag and drop the point in the editor, the point Y number is going to change because it’s not selected but the point X will never get changed unless you press somewhere in the white area of the box to deselect.
In this GIF, showing you how the X never changes if you didn’t deselect it (by pressing in the white area).
A fix in my opinion would be:
if the user pressed in the editor (the sprite points area)
or
if the user pressed on the points
