 The intent was to change the code in `_unique_and_monotonic` [here](https://github.com/pydata/xarray/blob/4f3128bb7266d1a6fdeaf20718ea3f8286fe041e/xarray/core/groupby.py#L258)

A good test would be make sure you get the same answer when grouping a DataArray of ones by a monotonically increasing variable (e.g. `[1, 1, 2, 2, 3, 3, 3]`) and the decreasing variable( e.g. `[3, 3, 3, 2, 2, 1, 1]`) ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1523260646
