Deactivating split map leaves large margin on right side of screen

[brucecrevensten]

See screenshot below. STR:

• Open fire map, skip tour
• Activate dual maps
• Deactivate dual maps

Expected: map re-centers Actual: it stays where it was, and that results in a big gap on the right side of the screen.

Touch hard to see but notice the zoom control in the upper right corner.

Note that this isn't exactly a bug, it's a consequence of the map having finite spatial extent at the outermost zoom level. One "fix" would be to recenter the map when the split maps are deactivated, but this would have other implications -- if you're zoomed in this doesn't really happen, and do we want the map to jump back to the center in that case? It's a little more complex than it first seems. One other approach would be to pick some kind of neutral background color instead of white, so that the map more clearly appears to have an "edge".

Discuss before working.
