Tiny navigation bug

When navigating through a score with the arrow keys in Write mode, I can’t seem to be able to go up from an artificial harmonic when it’s displayed as two noteheads (the “Normal” and “Pinch” styles). Down or sideways are fine, as is navigating on to the A.H. from any direction.

And right away, another one: using Tab to cycle the selection around a note doesn’t work when there are multiple playing techniques attached to it, in which case the selection will (eventually) get stuck on the second PT that was entered, even when there are more than 2.
