Thanks for flagging this. It was a bug, which I've now fixed in a PR.

My fix adds a `keep_attrs` argument to `interpolate_na` in order to be consistent with the rest of the API. That means to preserve the attrs you'll either have to pass `keep_attrs=True` explicitly, or set the global option with `xr.set_options(keep_attrs=True)`. I would recommend doing the latter, and then please raise another issue if you spot any other methods which don't preserve attrs.

I basically agree, but we're discussing the details of whether or not to change to this behaviour as the default over in #3891 .","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,599074389
