fix(map): the base layer switch stays in its corner when a place opens

Opening a place sent it from the bottom left of the map to the top, which reads
as the control moving house rather than as room being made. Nothing was in its
way: the inspector is a card centred between the sidebars and at most 800 wide,
so the corner it was clearing is one the card never reaches.

Both renderers, since the switch is not supposed to move when an instance changes
its map.
