> I learned a while back that Google Maps was moved from maps.google.com to google.com/maps so that when people gave location permission to Maps, Google Search could also use that permission.
This does not appear to be the case, at least on iOS Safari. I went to Google Maps, gave it permission, then went to Google Search and searched for “delivery near me.” It again asked me for permission.
I imagine browsers have special logic for misbehaving major websites baked in all over the place.
