> you can't change content that the user is currently looking at without any interaction done, unless that's to be expected from the user I think it’a more realistic to say that there has to be some latency bound in any user interaction. Clearly the result of any action is not instantaneous. Search boxes are tricky because the user isn’t sure what side effect typing an additional character will have - it could not refine the search or get a whole new set of results. If it’s not indicated to the user when the operation completes, then they can assume the former and then click at a bad time.
