My guess (untested) is that `ds.coords['z'] = ('z', data)` may be creating a `Variable` object instead of an `IndexVariable` by mistake.

Index coordinates (i.e., `IndexVariable`) are supposed to be calculated once, when they are added to an xarray object.

If they are getting computed via `as_variable` in `expand_variable_dicts` (which is called from `_get_priority_vars()`) then something has already gone wrong.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,252543868

The current behavior should require calling a `.preview()` method of some sort.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,252543868
