In percussion mode, MIDI velocity does not align on triplets or quituplets

My tracker account is currently blocked for some reason. I could not find a way to request an unblock.

EDIT: Tracker is now working.

When in MIDI percussive editing mode, the velocity markers (lollipops) for the triplets and quintuplets do not correctly line up. As you can see in the pic, they are slightly lagging a consistent amount. They work correctly using regular ‘sustained’ editing.

This was in Linux (Ubuntu 22.04 LTS) and Win10.
