On another computer that I was not logged in, something else happened. It didn't say log in, but the search results were displayed and then one second later it removed them and displayed an error message (which did not explain the problem, but it did not ask you to log in, either). I was able to view the search results by pausing execution of scripts using the debugger, though.
