This isn't about preventing a leak (the room is now public, so the nickname

profile in the user directory results.
I made this a Synapse test case rather than a Complement one because
I think this is (strictly speaking) an implementation choice. Synapse
has chosen to only ever use the public profile when responding to a user
directory search. There's no privacy leak here, because making the room
public discloses the per-room name.
The spec doesn't mandate anything about _how_ a user
should appear in a /user_directory/search result. Hypothetical example:
suppose Bob searches for Alice. When representing Alice in a search
result, it's reasonable to use any of Alice's nicknames that Bob is
aware of. Heck, maybe we even want to use lots of them in a combined
displayname like `Alice (aka "ali", "ally", "41iC3")`.
