Additional map features doesn't respect visibility

[Funguss]

The additional features tagging option tags features that can't possibly be seen, e.g. interiors of above ground labs, stuff around you when traveling at night without a floodlight, stuff in the subways.

Expected behavior

Ideally each kind of extra should have a degree of visibility. For starters though just having a check on whether the overmap tile was mapped would be a vast improvement. This wouldn't solve all cases (e.g. when downloading subway maps or when traveling by night through areas mapped via a lab console) but it would help.
