No, I saw that one, but this specific issue is not to do with position anchors or call outs; it assigns a negative vertical offset when there wasn't one. Furthermore, the vertical offsets are different for different elements; the legend offset is -1 and other text boxes are -2 and -3.
But, to your point, I did notice, too, that position anchors aren't consistent between elements, even though they were before. They are showing in one of the 8 spots they are supposed to be (that is, not just anywhere along the border, as in the bug you referenced), but each element is random on which of the 8 is actually chosen/set.
