Description
Fixes #4086
As noted at #4086, our antialiasing handling exposed a matplotlib bug for a pretty specific edge case. Regardless of this bug, it's a bit redundant to call
pyplot.contourwhen the data do not span the requested levels, so we should plausibly get a tiny efficiency gain by skipping it when not needed.Consult Iris pull request check list
