Comment (by jdemeyer):

 Replying to [comment:8 vdelecroix]:
 > Most important is the other question: why should we return `x.parent()`
 if it is not an element?
 Because some classes which really should be an `Element` aren't actually
 an `Element`. See #17578 for example. If all such bugs are fixed, we could
 remove that additional test.
