This is actually intentional, we don't want to 'leak' bearer
information if we are not discoverable over BR/EDR since when we are
just connectable we don't respond to inquiries then we shouldn't
advertise it either.
If the use case you want to support is to use an advertisement to
indicate to the remote end to connect over BR/EDR then it is probably
a better idea to make it discoverable on both bearers, then that flag
wont get set.
