Filters out the set of bundles that should not be visible to the bundle associated with the given context.
If the given context represents one of the allowed duplicates, this method filters out all bundles
that are duplicates of the allowed duplicates. Otherwise, this method filters out the allowed duplicates,
so they are not visible to other bundles.
