PRV keyboard still not lining up with MIDI rows in Ipswich 21.8.00 Build 33

I saw this the other day and just hoped it was a fluke, but no (and it's still happening with today's release).  In the piano roll view, the keyboard drawn on the left hand side is still becoming unaligned with the MIDI lanes.  In this screenshot you can see the mouse is on the first note (you can see the selection extending across) but the PRV keyboard is showing the text "C4" several inches below.  If I change the vertical zoom it will fix itself.  This bug was supposed to have been fixed with Ipswich but clearly is still broken.  This is Ipswich 21.8.00 Build 33.
