I don't think there are other cases where find works differently than
the traditional selector.
As it stands I don't really see a way to land this change in a way
that won't A) Slow down code and B) Provide weird and inconsistent
results.
Seems like it's probably a no-go. It's funny because I actually
thought about this issue a while back, hoping to try and find a way to
make this simpler, but was unable to think of a good solution. Guess
we're stuck with what we have, for now.
