There may be an issue with KRPano recognising WebXR capability in Wolvic. I've been in touch with Igalia directly but they believe it's a problem on the KRPano side.
As an example this Krpano example VR site has reversed head tracking.

When you run this test site in Wolvic on the Oculus Quest 2 it indicates that Wolvic has neither WebXR or WebVR capability but is a VR Browser. (in Oculus browser it shows both as available)
It is possible to force webVR in Wolvic and then it works but by default Wolvic want to allow only webXR.
Perhaps the device detection in KRpano needs to be adapted for Wolvic.
