Well, it'll initially connect to the database named in -d, issue DROP and
CREATE DATABASE commands naming the target database from there, and then
reconnect to the newly-created database to restore its contents. If you
can show that it's not doing that, that'd be grounds for a bug report
(with some backing details).

No, because dropping the database one is currently connected to is
disallowed. So --clean/--create *can't* work that way.

Don't use --create. Just give the existing target DB name in -d.
(You can use --clean if you want, but it's probably better to
drop and recreate the test DB manually.)
BTW, the behavior in this area changed a bit in v11, so be careful
you are reading docs that correspond to the pg_restore version
you are using. I don't think this specific thing changed, but
the overall division of labor between pg_dump and pg_dumpall
changed.
