I think it's better to add these now and check in the FAIL expectations. That
way the fix is forced to clean this up and we can catch any other regressions.

+assertInterpolation({
+  property: 'shape-outside',
+  from: 'circle(20% at right 10% bottom 20px)',
+  to: 'circle(30% at right 20% bottom 30px)',
