Play back mordents on notes shorter than eighth

Mordents don't play if the note is shorter than an eighth. This to me is wrong.

16th notes should be able to have mordents on them played back since a 16th note mordent(just the normal type) is 2 64ths and 1 32nd. Same for 32nd notes with mordents but this time it would be 2 128ths and 1 64th. These should be perfectly supported.

I don't understand why this hasn't already been added.
