The Baerenreiter edition also gives this note as d1. To my ear it is
more correct since it establishes the chord on the second quarter as
a first inversion d chord (the subsequent treble f'', a', c'' figure
turns it into a 6-5 and, since you avoid the implied parallel fifth
that results when one simply moves around in root position triads,
all's right with the world). But it does look weird, I'll give you
