Wrong playback after applying cross-staff notation with glissandos in Diatonic play style

As seen in the below score, a bug can be observed in the playback of specific glissandos. This appears to occur when a glissando spans over two staves AS WELL AS changing clefs. I have only noticed issues when selecting the DIATONIC glissando.

To reproduce this issue:
1) In a score including a two staved instrument (e.g. Piano, Harp), with different clefs, insert one note in the bottom line, directly followed by a higher note in the same stave.
2) Insert a glissando on the first note, and in the inspector, change the Play Style to 'Diatonic'.
3) Select the second note, and then press [cmd/ctl + shift + up], to move the note between staves
4) Play from the first note

*This also works descending, starting in the top clef, and [cmd/ctl shift down] on the second note, resulting in the same bug being produced

The score attached includes:
a) A Diatonic gliss in the same stave, with the same clef
b) A Diatonic gliss in the opposite stave, with the same clef
c) A Diatonic gliss in the same stave, with a different clef
d) A Diatonic gliss in the opposite stave, with a different clef ---> Which appears to be the issue
