Cursor position should reset when exiting a window.

[visualcode-t]

Bevy version

0.4.0

Operating system & version

Windows 10

What you did

After placing multiple ButtonBundles which change on Interaction I removed my cursor from the screen and began to resize the window.

What you expected to happen

I expect that the currently hovered ButtonBundle lose its hover.

What actually happened

Not only does the currently hovered ButtonBundle remain hovered, but, it also transfers that hover to other ButtonBundles as the window resizes, if those buttons move to where the mouse had been.

Additional information

When the window is resized, I have the buttons scale and move to match the new window size. So, the placement and size of the buttons does move around.

I think this should be fixed by #3926. If that's not correct, please comment and someone will re-open this (or re-open it if you have permissions to).
