Fix the current location error on iOS #249
Description
(I am not sure how many people have the same problem I have, maybe I am just incompetent.)
Using the deployed version of the navigation on Safari on my iPhone, I can not access my current location, even though the permissions allowed it and Chrome did it just fine. I get the error Geolocation error: User denied location. If this is indeed an error, it should be fixed, especially because the map will typically be used mainly on mobile where the share of people with iOS and Safari as their main browser is significant. Also check, if it works on mobile with Android, although chrome will be used there much more often.
