MapAPIKey required for single contact "Map", not for batch "Map Contacts"

First - set up to use Google as the Mapping Provider, but do it with an empty "Mapping Provider Key". Have all the member locations geocoded.

Then, using the "Search" and then "Find Contacts" from the CiviCRM menu - perform a search that will have multiple search results (rows).

When the result comes in, at the top, at "Select Records:", choose "All [x] Records", where [x] is the number of records. The "Actions" for bulk actions has a choice "Map Contacts". This works. But at each row, on the far right, the "More" menu will not include "Map" unless there is a Mapping Provider Key.
