Well, as usual after multiple days of trying to figure it out without asking for help, I figure it out myself literally 10 minutes after asking for help.

For anyone having this problem, on firefox at least it can be remedied by rolling back to legacy WebVR code:
>enter About:config in browser bar
>search dom.vr.enabled
>flip to true
>If WebXR API Emulator plugin is enabled, disable
