reverse: search position on map not updated after no-result search

[mtmail]

1. Reverse search with no result https://nominatim.openstreetmap.org/ui/reverse.html?lat=71.3000&lon=22.2500&zoom=18 shows a red circle on the map
2. Fill form lat=-77.9564, lon=166.7667 and click 'Search'
3. The red circle didn't update and still points to the previous position
4. Page reload (browsing to https://nominatim.openstreetmap.org/ui/reverse.html?lat=-77.9564&lon=166.7667&zoom=18) shows the correct position again
