This approach works for some cases but not for all. It doesn't properly consider scaling when checking if it's in the visible area.
For example, I can reproduce the same issue if I set the scaling on my primary monitor to 300%, connect the second monitor to the right, and open the Editor on the second monitor. After disconnection, its position won't be reset.
