Request frames again while waiting for tiles and transitions

A request-mode globe updates its tile state only on drawn frames, so tile
and UI readiness that never asked for one waited until something else
drew: imagery, weather and ground scenarios took several times longer.
The idle checks measure through their own passive observer and are not
affected.
