Which behaviour can you reproduce?

Replacing `mean` with `std` in my last example passes the identical check. Actually this works too

```
a_ds = ds.groupby(""y"").apply(lambda x: x).a
a_da = ds.a.groupby(""y"").apply(lambda x: x)
a_ds.identical(a_da)
```

The transpose is fine, I think. It looks intentional and must be consistent with other Dataset/DataArray operations?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,522523336

Re: docstring. If you jave time, can you add a couple of examples (just pick two from the tests) to illustrate the scalar vs vector behaviour of `q`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,522523336
