Yes, because you're asking a client for text and images downloaded from a server to do things it was never intended to. When you start employing torturous misuse, you're going to find the tool unsuited to the job. You can use a pipe wrench as a makeshift hammer, but a sledgehammer can't tighten a nut (more than once).
