How to reproduce it :

• edit a news content of the demo repository,
• Clic on the geolocalization field
  > a popup is opened. Enter Toulouse city : the cursor appears on the Capitole
• move this cursor with the mouse to the stadium (the moving action is quite difficult)
• then try to put the cursor in another place of Toulouse
  > At the end, that arrive a time that the map is scrolling alone and your cursor probably will finish in north pole
