Summary: camera_rotation Molang query visibly lags behind during rapid camera movements.

Affects currently Live Content: Yes

Impact: When animating something in-sync with camera rotation and position, the slightest desync can be quite apparent and visually distracting. This issue affects our live add-on and makes one of its features seem not as fluid as it should've been.

Repro Steps:

1. Set max framerate to 30 in Minecraft video settings (Settings -> Video -> Framerate limit)
2. Create a new world with attached add-on and enabled cheats
3. Run /summon example:bug command in chat
4. Rapidly rotate camera while looking down

Observed Results: Entity geometry seems to lag behind during rapid camera rotation (see attached video)

Expected Results: Entity geometry would appear perfectly stationary on screen as it would use current correct camera rotation

Screenshots/Videos attached: Yes, video is attached
