Actually, i can understand why this output is _wanted_, but can not imagine
good Summary for issue report.

"Rest in lower voice should be placed above notes in in upper if voices are
crossed"? Or if lower voice's noteheads are above the middle line, while
upper voice's stems are staring from the middle line?

I am not sure that either is correct.

Can anyone help me?

Or i've missed something badly?

Thanks.
