Issue with cross-staff notation (MuseScore 3.0.1)

Hello there,

First time posting anything on the Musescore website; please forgive me if this is a known issue.

I am writing a piano score in which the top staff contains a melody in eight, quarter, and half notes and in which the bottom staff contains an accompaniment in sixteenth notes. I would like to have both voices displayed on the top staff. In Musescore 2, I would simply select the bottom staff and use Command+Shift+Up to accomplish this.

If I try this in Musescore 3.0.1, all of the beams of my sixteenth notes disappear. The music does render correctly if at least one note per group of sixteenth notes stays on the bottom staff, but that isn't the desired outcome.

Thank you in advance for any help resolving this issue!
