yes, the realm is applied recursively, but the comment-as-realm is not.
that is: if the item has no realm, the realm is searched in the parent, and in the parent of the parent until it is found.
the same work is not made when the comment is used as realm. only the comment of the item is used, if it is empty, no way, it stops there and don't search anywhere else.
this is a possible problem. it may be not what the user expect to get. but maybe it is.
please, express yourself, i like to know anyone's opinion.
