grid container with shape circle doesn't position cells correctly

[gavin-ts]

for grid containers that have a shape: squares and circles should maintain their aspect ratio and fit contents inside each shape's inner box.

Previously shape's were fit to content without label/icon, and now they are fit including the label/icon after #1731, but the positioning isn't always correct particularly with shape: circle

Note that this is for grid containers specifically ( dagre doesn't have this feature, only constant padding but #1648 might be able to help)
