Yeah, and 'unsniffing' too. See my old <object> test, at <http://santek.no-ip.org/~st/tests/object/>. All three images are the exact same PNG, served with Content-Type: image/png. Yet with @type="image/*" both Firefox and Safari don't present the image. Safari presents the fallback, Firefox presents nothing. Is this a simple bug, or by design? I thought the sniffing is done because http content-type isn't trusted. But this seems to be a case where @type is trusted more than http content-type; even so much more that apparently no snniffing takes place. -- Sander Tekelenburg The Web Repair Initiative: <http://webrepair.org/>
