Problem summary

In measure 7 of https://verovio.humdrum.org/?file=chorales/chor001.krn there's a fermata. In the same measure, the chorale continues. The note after the fermata has as measure 0.

# to reproduce
score = m21.converter.parse('chor001.krn', format='humdrum')
for element in score.recurse().getElementsByClass([m21.note.Note]):
    print(
        element.pitch.step,
        element.pitch.octave,
        element.pitch.accidental.alter if element.pitch.accidental else 0,
        element.quarterLength,
        element.getOffsetInHierarchy(score),
        element.getContextByClass('Part').id,
        element.activeSite.measureNumber
    )
    
    if element.activeSite.measureNumber == 8:
        break

# results in

B 4 0 1.0 16.0 spine_3 6
A 4 0 2.0 17.0 spine_3 6
G 4 0 2.0 19.0 spine_3 7
B 4 0 1.0 21.0 spine_3 0   <------- 0 in stead of 7
B 4 0 1.0 22.0 spine_3 8
