And of course, in the case you insert into a real table you expect if a
trigger procedure suppressed your original INSERT, but fired a cascade
of other triggers by doing a mass UPDATE somewhere else instead, that
all these caused UPDATEs and whatnot's are summed up and returned
instead, right? Or what is proper behavior here?

So please, "proper behavior" is not allways what your favorite tool
expects. And just because you cannot "fix" your tool doesn't make that
behavior any more "proper".
