Not sure if this should be reported here or at xviewer-plugins.

Map plugin does not work with images that have GPS info.

Steps to reproduce

1. Go to Edit / Preferences / Plugins and enable the Map plugin.
2. Open image file with geolocation info / GPS coordinates, such as this
3. The help page describes that there should be a map of the location in the Side Pane:

Expected behaviour
There should be a map in the Side Pane, or at least some way of opening the GPS location in the browser, as described on the Map plugin's website
