The source of the bug is that encoding metadata `chunks` (which describes the chunk size of the underlying zarr store) is automatically getting populated when you load the zarr store (`ds = xr.open_zarr('data.zarr')`), and this encoding metadata is being preserved as you transform (sub-select) the dataset. Some possible solutions would be to
1. Not put `chunks` into encoding at all.
2. Figure out a way to strip `chunks` when performing selection operations or other operations that change shape.
Idea 1 is easier but would mean discarding some relevant metadata about encoding. This would break round-tripping of the un-modified zarr dataset.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,340192831
