Description

We need to make sure that the old and new HJ nodes can do intra-fragment filtering (i.e. if the probe scan is in the same fragment as the HJ). We can achieve this by short-circuiting delivery of broadcast filters in the RuntimeFilterBank - the other part is to ensure that filters are always computed by the front end.
