Ensure contentInset honors UI at bottom of map

Need to move the UI to the bottom of the map anyway, so this may be simpler once that's done.

Will need to wait for update to the Runtime. Perhaps Update 2.

@nixta It appears bottom UI does honor the safe area. Unless of course you're referencing something else?

Can I close this issue out?

Let's keep this open for now. I'm referring to the route appearing behind the UI at the bottom. Unfortunately right now the ContentInset on the MapView moves the entire attribution bar up, which in turn moves the UI up to once more cover up the route.

Could wait for Runtime to fix, but in the meantime could do a manual extent calculation to fit the geometry to the unobscured map area.

Noted. Let's consider the manual extent calculation.
