Default Notation editor - changing default display clef moves note positions in time (FIXED)

Windows 10 64-bit, Reaper 5.92pre2/x64

Noticed this one working today, and I thought I'd better make a report because I've never seen it before and would probably lose track of it.

I changed the default clef of a track and the notes were shifted in time to the right by what appears to be an exact dotted 32nd note.

Additional details: the midi item for the bass clarinet begins where the edit cursor is positioned, as you can see at the beginning of the gif. When the clef is changed, the start of the midi item is moved earlier. Time signature in this section is 9/8, if that makes a difference.

Also, performing an undo operation once will actually move the start of the midi item and the notes back to the correct position, but the clef change will not be undone until a second undo is performed.

I consider it fairly serious because it is possible to change clef of a track without any notes in view, and not notice that notes were moved incorrectly.

Can you post a little bit of MIDI that will let us reproduce the issue?

I don't think there's any way that changing the clef would actually move the underlying MIDI notes, I think it's just the way they are notated that changes, but we can figure out exactly what's happening if we have a way to reproduce it.

I reduced the project to one track and attached that here. Exporting to midi did not allow me to reproduce upon import to a new project. I think it may have to do with the time signature and tempo changes in the project? Also notice that in the gif I change the default clef by clicking in the bar before the midi item actually begins

Thanks for posting the project. As a workaround for now, the problem should not appear if you first drag the start of the MIDI item one bar earlier. The clef change is itself a MIDI message, so the weirdness is caused by REAPER automatically extending the MIDI item to fit the new message in.
