@TomAugspurger @jbusecke is seeing some funny behaviour in https://github.com/jbusecke/cmip6_preprocessing/issues/58

Here's a reproducer ``` python import dask import numpy as np import xarray as xr

dask.config.set( **{ "array.slicing.split_large_chunks": True, "array.chunk-size": "24 MiB", } )

da = xr.DataArray( dask.array.random.random((10, 1000, 2000), chunks=(-1, -1, 200)), dims=["x", "y", "time"], coords={"x": [3, 4, 5, 6, 7, 9, 8, 0, 2, 1]}, ) da ```

Which is basically

python da.data[np.argsort(da.x.data), ...]

I don't understand why its rechunking when we are indexing with a list along a dimension with a single chunk...
