Instead of using spatial_dims method to get names of spatial dimensions, can you please use xx.odc.ydim to obtain location of the y-axis (x-axis always follows y) and expand rasterized using that.

non_sdims = (*xx.dims[:ydim], xx.dims[ydim+2:])

sdims = spatial_dims(xx, relaxed=True)
non_sdims = {}
non_sdims_axis = []
for i, (k, v) in enumerate(xx.sizes.items()):
if k not in sdims:
non_sdims[k] = v
non_sdims_axis.append(i)
if non_sdims:
rasterized = rasterized.expand_dims(non_sdims, axis=non_sdims_axis)

# Mask data outside rasterized `poly`
xx_masked = xx.where(rasterized.data)
