This appears to be flaky, or at least the duration is. I left the page open for a long time and the camera did not go away. Then I refreshed and repeated steps 4-6 a few times. The indicator seemed to last for 12, 20+, and 30+ seconds.

When the indicator is visible, the permission toast is displayed when entering WebXR presentation, but it is not displayed when entering after the indicator has disappeared.

Outside VR, in traditional 2D browsing, both the camera and mic icon in the system tray disappear after some period of time. Thus, this doesn't appear to be VR specific. I have not been able to reproduce this on https://permission.site/ in 2D.

In my most recent attempt on the test page in 2D, the mic indicator disappeared after about five seconds, then I clicked the camera and that indicator is still visible after over a minute.

This may be due to the fact that the site isn't actively using the camera, just requesting permission to access it and then letting the result fall on the floor.

Maybe the thing that provides access is being garbage collected because there is no reference to it. That would explain the random behavior. Would attaching it as a property to some global object resolve that? We could also look at what https://permission.site/ does.

doesn't sound like it's MVP, removing from hotlist.
