When testing the webxr_vr_layers exemple in a certain way, a blocking bug occurs.

To Reproduce

  1. Visit https://threejs.org/examples/?q=layers#webxr_vr_layers with a VR headset.
  2. Click "Enter VR".
  3. Update eyeChartDistanceFt value in the GUI.
  4. Press the menu button and exit immersive VR.
  5. The console logs Uncaught TypeError: Cannot read property 'getSubImage' of null.
  6. Click "Enter VR" again.
  7. Black screen. The console logs Uncaught DOMException: Failed to execute 'getSubImage' on 'XRWebGLBinding': Called getSubImage with objects from different states.

It's coming from this line

Note the the bug does not occur when you omit step 3.

Tested on Oculus Quest 1.
