Yes it now fails here with maxNumObs=1 and xarray main.

It looks like `self._chunks` is wrong but I don't know why.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1249638836

```
dask  : 2022.3.0
zarr  : 2.10.3
numpy : 1.21.5
xarray: main
```

Can you try downgrading zarr to `2.10.3`? Does it still fail for you with `maxNumObs=1`? I don't see a commit that would've fixed this on xarray main... And I don't think dask is involved here.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1249638836
