E Mouse Unlock - Mouselook is lost if you press F to interact with a chair while holding E

Mouselook is lost if you press F to interact with a chair while holding E, even after the menu is closed.

When using `E` to engage camera-lock, if you use the `F` key to open a station on-screen menu the camera-lock does not release even if you are no longer pressing the `E` key, or after you have finished using a station's on-screen menu.

Its like, the input-state flag for camera-lock isn’t being reset when the station on-screen menu takes focus. it doesn't notice the `E` was released once you press the `F` key. (I have no clue how this is layout, so I probably shouldn't even mention it :) ((Also no laughing at my puny old computer :))

Steps to Reproduce:
Sit down at a console - press E- then press F4 - you are then able to move it around with the camera. Although, one is able to press F4 and then E again to release.
