Zarr-python 3 cannot read old data with empty channels #335

Description

@ziw-liu

Using zarr.open() from zarr-python 3.1.2 to read Zarr v2 data gives all zeros. Only 1 out of 3 channels should be empty (due to czbiohub-sf/biahub#120).

We need to come up with a minimal repro and file an upstream bug.
