Bug Mouse position reset when window loses focus

Hi, it seems like whenever the game window loses focus, the mouse position Vector2 gets set to (0,0). This makes your mouse position snap to the bottom left instantly. I see in the changelog for version [1.1.0-pre.6] there is a comment saying this(?) was fixed: Controls such as mouse positions are no longer reset when focus is lost.

However, this seems to be exactly what is still happening. I'm using Version 1.4.4.
