After debugging we found that zarr.core.Array._encode_chunk() does not encode chunks, if both compressor and filters are missing,

However I could not reproduce our problem with Zarr open/save alone. It seems to occur only when using xarrays.open_zarr() and xr.Dataset.to_zarr(). Therefore I seems to be an xarray issue rather than a Zarr one.
