Zoom to viewbox when 0 results

https://nominatim.openstreetmap.org/search?q=CVS&addressdetails=1&viewbox=74.01%2C39.01%2C72.01%2C41.01&bounded=1 gives 0 results because the viewbox is in Kashastan (user expected it to be in New York City). The (green) viewbox is on the map but hard to see. Better to zoom in to the area to make the mistake more obvious.
