Zoom out functionality on projects list page not working correctly (back action)

          While I no longer encounter the "Ressource not found" issue, the map is not really zooming out now, and is basically "stuck" on Africa. Tested in normal browser-window as well as incognito.

When I open up a project details page directly and press back, the user is taken to the home. The map is supposed to zoom out to the default position. However, this does not happen, and the map appears zoomed in to Africa.
