Bug: `momentary_rot_button` does not function usably

[Equalizer5118]

Describe the bug

momentary_rot_button is supposed to rotate to an arbitrary position and then be able to move a func_movelinear to a position relative to the rotated button. This movement logic works, but the button does not function correctly. it stops rotating very shortly after being pressed, even when holding down the use key.

Here is a video comparing Half-Life 2 and P2CE behaviour. This is also apparently the case in Portal 2, but I have not tested that yet.
