Changing name filters in QFileSystemModel does not trigger e.g. rowsInserted signal

QFileSystemModel has name filters. These filters can either disable or remove items. When it removes items, changing the name filters results in rows being removed and/or added. This should trigger the signals rowsAboutToBeInserted, rowsInserted, rowsAboutToBeRemoved, and rowsRemoved. But these signals are not emitted.

A little reproducer is attached.
