Better to just duplicate that one line from the default implementation, instead
of calling it explicitly from here. (Because it's easier to read, and that's the
behavior you want regardless of what the default behavior was. But see also the
question of whether this default behavior may be what everyone wants all the
time.)

Done.

Same.
