They show the page and then block it from you afterwards, so if you load the page then keep spamming the escape key to stop anything else from running the content will stay there. Therefore my guess is that your 6th time it just happened to not work (maybe you accidentally hit escape, maybe your browser decided not to execute a script, or your internet timed preventing it from doing so, or....) - but I could be wrong.
