Describe the defect
When pressing Escape to open the pause menu while in fly mode [tab] in the planetary system simulation, the mouse remains locked i.e. you don't see it and moving the mouse just moves the camera

To Reproduce
Steps to reproduce the behavior:

1. Go to Planetary System
2. Click on Simulation
3. Press [Tab] to enter fly mode
4. Press Escape
5. Mouse still not usable to press anything in the pause menu

Expected behavior
I expect the mouse to be usable again when pressing escape, then when I would close the escape menu again, i would expect the mouse to be "locked" again
