I suspect the problem is in `Variable.copy` on [these lines](https://github.com/pydata/xarray/blob/22ff955d53e253071f6e4fa849e5291d0005282a/xarray/core/variable.py#L467-L469) (which should probably just be removed). Coordinates store their data in `pandas.Index` objects, which are supposed to be immutable. But apparently that's not necessarily the case.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,237807730
