xarray.VectorWind gives strange error when u- and v- components have different extent about windspharm HOT 2 OPEN

This test looks wrong to me, I don't think the .all() should be there. You'd know more about comparing xarray coordinates than me, what is the best way to write this? I don't really use xarray much, and I implemented this whilst still learning how xarray works, errors and areas for improvement are inevitable.

I think this is actually a pretty reasonable way to compare coordinates. And, if my guess is correct, this is actually a subtle NumPy bug/issue: arrays of different length compare as False instead of raising TypeError when compared.

I would simply replace (uc == vc).all() with np.all(uc == vc). That should fix the bool issue.
