### Any additional comments?

_No response_

Start with the linked minimal reproduction and inspect pie-chart labelLayout handling for moveOverlap set to 'shiftY' when every data value is zero. Compare the current label positions with the expected alignment in the reproduction; done means the labels remain aligned without the positional shift.
