WebXR controllers disappear after interacting with controllers during paused session

[s0564704]

Description

Description

WebXR controllers completely disappear (both visual models and input functionality) when interacting with controllers while the session is paused, then resuming the session.

Reproduction steps

Environment

• Device: Meta Quest 3
• Browser: Meta Quest Browser

Steps to Reproduce

1. Open a WebXR example (tested with: https://threejs.org/examples/?q=webxr#webxr_vr_sandbox)
2. Enter VR mode
3. Press the Meta button on the right controller to pause the session
4. While the session is paused: Use one controller to target the other controller and press the trigger button
   Also happens when targeting some elements on websites.
5. Resume the session

Expected Behavior

Controllers should remain visible and functional after resuming the WebXR session.

Actual Behavior

• Controllers completely disappear from the VR scene (visual models are gone)
• All controller input functionality is lost
• Hand tracking (if enabled) also stops working

Workaround

Pausing and resuming the session a second time restores both controller visual models and functionality (works almost always).

Its bugs with the OS for a month now. Which they keep regressing. Press menu to exit XR then press resume to get back in. Still a problem on v78. A few versions back it was staying connected between sessions.
