Serverside pl:GetAimVector issue when using Context menu

[penolakushari]

Came across an issue with GetAimVector, appears serverside when player is using C-menu and their aim angle at world's pitch axis is 0 or close to it, it results in jerky movement which can be observed in vanilla tools' ghost previews, like thrusters or wheels, and the vector that is being returned doesn't seem to go between 0.02 and -0.02.
Clientside function works without such issues.

I've also took some print()'s when moving the aim vector around when the issue was happening:

GMod version: 2024.08.09
Tested it on current live version and 64 bit branch, issue persisted, same without addons.

Steps to reproduce:
Can be done with anything that gets player's "GetAimVector" serverside, primarily vanilla tools that spawn ghost previews for their entities.
With the tool out, open context menu, and try to move the cursor around the game area, and it should have that jitter/deadzone around the 0 pitch.

Video shows how it behaves on my end with Wheel, Thruster and Ragdoll Mover tools.

This is just float imprecision issue, due to the reduced precision the world clicker aim angle is networked at.
