I don't think there was any particular motivation behind the
double-click interaction. I was mostly trying to reproduce exactly how
Qt creator's locator worked, so that's likely what drove that
decision.

That said, we'd need to ensure we don't break keyboard only
interaction by a move away from the double-click activation.
