Handtracking switching on Quest causes lasers to displace position and rotation

[SpookySkeletons]

Description

This used to work previously but changed in a wlx0overlay-s revision mid-way through to wayvr rename.

When handtracking switches between states wayvr's lasers will displace by some degree from their intended pose likely depending on how the user moves hands during the process of changing interaction style.

Stilling the controllers, opening the quest menu with the meta button, then closing it again while keeping hands still can reverse the effect.

Are you using custom binding for simple_controller or ext_hand_interaction?

By default, WayVR doesn't do HT lasers. Only controllers, HMD and eye-tracked laser is supported.

I'm not sure how hand tracking would affect the aim pose of the lasers, unless it's a quest system bug.

I am using all defaults for controller settings, however, hands do actually track a laser that responds to pinch input.
Is this unexpected?

Issue still present despite bindings change, my changes may be reverted as they do not actually address the bug.

Bisect of all wlx commits a year ago reveal WiVRn has the bug here between versions 25.11.1 and 25.12: WiVRn/WiVRn#785
