Yes broadcasting is doing alignment with outer join by default: https://github.com/pydata/xarray/issues/6304. This is conceptually pretty confusing.

I agree we should document this.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1499473190

My expectation was something that operated more like numpy broadcasting (repeating values, not filling with anything else).

I can understand how xarray's data model yields this behavior, but in that case it might be good to improve the docs for `xarray.broadcast`, because it says nothing about the behavior that (seem to me) mimics `xarray.align`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1499473190
