That usually works, but not always.

  It may fail, when the object was accessed via acquisition.

The other proposal ("getParentNode") may be more reliable
(as acquisition context might be cut away) but I am not sure
(acquisition rules for a method's "self" are so complex that
I always need to think for hours how they work in a concrete
situation).
