Geolocation spoofing working inconsistently in several online mapping services

[whatbh]

"Find my location" feature on a few sites (OpenStreetMap, Google Maps, browserleaks.com/geo) does not work at all when Geolocation API is enabled in JS Restrictor.
Quick check in web console shows this error upon requesting location (Figure 1)

Uncaught TypeError: 'getCurrentPosition' called on an object that does not implement interface Geolocation.

Figure 1: Error in web console upon location request.

Specifications: Firefox 98 on MacOS. Tested another alternative addon "Location Guard" and it worked fine.

Can you tell me your browser and JSR/JShelter version you use?

Several updates have been released from last time. I tried again with Firefox 99 Nightly and JSR 0.7. Here's the more detailed report.

Tried with fresh Firefox profiles, no extension except JSR, one profile with resistFingerprinting enabled, the other with RFP disabled, both reproduce the same result.

Levels/Services	Google Maps	Bing Maps	HERE Map	OpenStreetMap	https://browserleaks.com/geo
Turn off (Negative control)	Can locate normally	Can locate normally	Can locate normally	Can locate normally	Can locate normally
Village	Can locate normally	Can locate normally	Can locate normally	🚫 Error	🚫 Error
Recommended (Town)	Can locate normally	Can locate normally	Can locate normally	🚫 Error (Do not show popup request location, show error in console)	🚫 Error (Do not show popup request location, show error in console)
Region	Can locate normally	⚠️ Work sometimes	🚫 Error	🚫 Error	🚫 Error
Long distance	Can locate normally	⚠️ Work sometimes	🚫 Error	🚫 Error	🚫 Error
Strict (Positive control)	🚫 Error	🚫 Error	🚫 Error	🚫 Error	🚫 Error

Conclusion: Some how it does not work with OpenStreetMap and "https://browserleaks.com/geo". Maybe I should update the title.
Update: At "Region" and "Long distance" levels, it's sluggish with Bing Maps, works intermittently, and with HERE Maps it doesn't work at all.
