hand-controls misaligned with HTC Vive controllers in 1.4.2

Description:
As of commit 5b29ac2, the hands no longer line up with the HTC Vive controllers.

This is the log for the specific commit in which the issue first appears:

hand-controls: rotates models to match WebXR definition (fix #4848) (#5261)

It is a small commit that only changes handModelOrientation. It seems the Vive is not in agreement with the new WebXR standard. Is this an issue that exists at the level of SteamVR and their WebXR implementation? If so, maybe a workaround is possible in the mean time?

Note: Due to an issue with the build bot at the time, you won't see the issue in the cdn.jsdelivr.net link supplied for commit 5b29ac2 or any other commit before 7050d7b (the last April 19th commit). You'll have to remake the build yourself if you want to try those commits for any reason.

• A-Frame Version: 1.4.2 (5b29ac2 and up)
• Platform / Device: gen 1 HTC Vive / Windows 10 / Steam VR 1.26.3 (beta) / Chrome 114

Start by examining the hand-controls change from commit 5b29ac2, especially handModelOrientation, and compare its behavior with the HTC Vive and SteamVR setup described here. Determine whether the misalignment comes from the WebXR orientation change or the Vive implementation; done means controller hands align again without regressing the WebXR behavior.
