Re-reading from a consolidated store

[ilan-gold]

So I need to re-open a zarr Group from an already existing array (that comes via consolidated metadata). But the result is giving me zeros (which is not expected). I have a little example:

import zarr
import numpy as np
g = zarr.open('test.zarr')
g['foo'] = np.arange(0, 10)
foo_from_store = zarr.open(store=g['foo'].store, path='foo')
foo_from_store[...] # correct, arange-d
zarr.consolidate_metadata('test.zarr')
g_consolidated = zarr.open_consolidated('test.zarr')
foo_from_store_consolidated = zarr.open(store=g_consolidated['foo'].store, path='foo')
foo_from_store_consolidated[...] # incorrect, all zeros
g_consolidated['foo'][...] # correct, arange-d

I must be doing something wrong, but cannot say for sure. Any help appreciated! Happy to provide a PR if that's needed!

For anyone interested, the answer is to do the following:

foo_from_store_consolidated = zarr.open(store=g_consolidated['foo'].store, path='foo', chunk_store=g_consolidated.chunk_store)
foo_from_store_consolidated[...] # correct, arange-d

I don't think this is a bug, but I wonder if the behavior should be clarified in that you can't actually read chunks from a consolidated metadata store: https://zarr.readthedocs.io/en/stable/api/storage.html#zarr.storage.ConsolidatedMetadataStore.
