This particular test will succeed because the net effect is that the sniffer forever thinks it's in head section - so the detection of charset works fine, however if there is no charset, the detection never stop and detector accumulates the whole page (scanning through whole of it multiple times perhaps) before giving it to parser when the data load finished.
