Take advantage of a new function we defined already for what nodes are
"interesting" on Android.

When we get a hit test result back and it's not interesting, first see if
there's a single child that's interesting. If so, return that. If not,
walk up to the first interesting ancestor.

That will avoid returning something like a wrapper <div>.
