Abrowser: Cannot share Location

I cannot share location in Abrowser like in Firefox (see the screenshots). Try https://whatmylocation.com/ for example.

I could not find anything privacy related to "location" at https://trisquel.info/en/wiki/abrowser-help, just " By default, Abrowser resets browser geometry and zoom level, as privacy features. If you wish to disable these features, you can do so by going to about:config and changing privacy.resistFingerprinting to False." -- so this location issue should not be related because it is common to use web services that utilize the location.
