**Short story**
We need a control to convey the idea of **going back to the initial position of the map** - the fixed zoom and position as it is saved in wikitext.
**Long story**
Maps are interactive. An editor initially configures a **zoom**, **longitude** and **latitude** for the center of the maps.
Once loaded, the user can play with the map: move the center of the map away from its initial position, zoom in or zoom out.
Since T135556, a user can also **share** a full screen map, at the zoom level and position he is currently looking at (different from the initial position configured by the map "creator/editor").
Without a dedicated control, a user has to reload the webpage in order to go back to the initial position.
We want to provide an easy way for the user to retrieve the initial position without reloading the entire webpage. The action itself can be done very easily with JS, the only question is where on the UI, and on wha element, should the user click to trigger the action.
**Requirements**
- The control/action will be displayed **only when** the current position/zoom **differs from the initial one**.
**Questions**
- Should we have a label displaying on top of the map such as: "Back to initial position" (similar to )
- Can we have an icon, without text, that can convey the idea?
- Which position? (please stick to //top/topleft/left/bottomleft/bottom/bottomright/right/topright//)
