[~hachikuji] I am wondering how polls can be introduced into the test so that a missed heartbeat
can be seen without the fix.

Typically this is not a problem because ListOffsets requests are handled quickly, but in the
worst case if the request takes longer than the session timeout, the consumer will fall out
of the group.
