Is this also for Standard Filter issues? (Asking because you can access Standard Filters from Data > Standard Filter, not only from the AutoFilter dropdown)
There's no separate Standard Filter META bug, but the parent META (bug 109326) is for data filtering in general, and thus is more appropriate for bugs specific to Standard filter.
