Jumpy playback cursor
Might be a regression against 2.x but I see it on 3.2.3 and 3.6.2:

Play it; at the end of measure 2, the plaback cursor shortly jumps back from the last to the second-to-last note before passing into measure 3. This should not happen; the playback cursor is a function of time, whereas the currently-played notes are instead highlighted in blue.
