Addresses with required custom fields can't be deleted from the Edit screen

Steps to replicate:

• Create a custom field set for addresses. Mark at least one field required.
• Create a new contact with an address. Save the record
• Click "Edit" on that record.
• Press "Delete this Address".

You will receive a message that the required field must be filled out.

This is relatively trivial because the workaround is to use in-place editing, but since a client stumbled across this, I wanted to pass it on.
