Some articulations on vocal part noteheads are causing playback to hold the note indefinitely

Hello, I've just upgraded to Musescore 4 and while it's pretty great I noticed an issue with playback that wasn't in version 3.

If a vocal part has notes with certain articulations (in my case the "open" symbol which looks like º) it holds the note indefinitely after playing it.

The symbol's main purpose is to signify playing on an open string for string instruments and on those parts it works fine. In my score I'm using this symbol in a vocal part, to denote singing it in falsetto.

I've attached an example score to demonstrate the issue. In Musescore 3 I was able to use that symbol and the playback was fine, so I'm assuming it's a bug.
