A question regarding microtonality and playback

Hi!

I have decided to try and make a piece that includes quarter tones, and I noticed that, during playback, Musescore doesn't seem to play the accidentals I have put on the notes.

For reference, the accidentals I am using are "Reversed flat (quarter-tone flat) (Stein)", "Reversed flat and flat (three-quarter-tones flat) (Zimmerman)", "Half sharp (quarter-tone sharp) (Stein)", and "One and a half sharps (three-quarter-tones sharp) (Stein)".

Also, the accidentals don't affect the playback or the piano roll editor, so I'm curious as to what is going on.
