Search results arrive asynchronously, which means that keypresses may
arrive before results do and therefore not have the effect the user
intends. That's especially likely to happen with the down arrow and
enter keys due to the one-off search buttons: if the user very quickly
pastes something in the input, presses the down arrow key, and then hits
enter, they are probably expecting to visit the first result. But if
there are no results, then pressing down and enter will trigger the
first one-off button. To prevent that undesirable behavior, certain
keys are buffered and deferred until more results arrive, at which time
they're replayed.
