/cc @gspencergoog I seem to remember that you recently also ran into the problem that "self" is not included when you look up ancestors. How did we solve the problem there again?

I created _getAncestor to fetch the parent so that I can start searching using getElementForInheritedWidgetOfExactType from the parent element, which avoids returning itself just by starting the search with the parent element.

And my problem was the opposite: getElementForInheritedWidgetOfExactType can return self, and I didn't want it to.
