If I am not misreading the scenario presented, then this expectation
is wrong.

This is totally expected.  Think of cloning from a bundle is just
like cloning from the original remote (limited to the refs included
in the bundle, of course).  Local branches of the remote (i.e. the
ones that corresponds to refs/heads/* you saw in your bundle) become
your remote-tracking branches.  Their remote-tracking branches are
not even visible, unless you explicitly ask "clone" to.  Which means ...

... this is not even a workaround, but how you would ask for their
remote-tracking branches.

Or 

    $ git init && git fetch repo.bndl "refs/*:refs/*"

which is like doing a mirror clone ("git clone --mirror").
