\cadenzaOff has "design artifacts" (various have been discussed here),
and \grace timing (our old friend) exacerbates the symptoms.

I don't think that it is worth filing a separate bug for the combination
with \grace.  Some of the recent examples involving \cadenza... might be
worth filing an issue for redesign.  It might be worth starting a
collection of them.  Basically it works as expected giving the
implementation (and never did something else), but I actually have a
hard time imagining even a single case where it would actually do what
you'd want.
