Not sure how to test this.

@mathause any thoughts on how we could test this?

The MWE in #3569 throws an error after #3916 (ValueError("Cannot supply vmin and a norm with a different vmin.")) - maybe it is enough to test that it works again?

I reverted to before #3569 and tried to figure out the difference in the QuadContourSet in terms of norm and some other properties of h and facet._mappables[0] is and couldn't figure it out.

h = ds[0].plot.contour(levels=[4], colors=['k'])
facet = ds.plot.contour(col='time', levels=[4], colors=['k'])

Confirmed. I have added this as a test. Thanks.

Yes I could not figure what the difference was either...
