Attachment: "minimal testcase"

Confirming. The offending element is actually a Java applet. The attachment is
not really a minimal testcase because it still refers to the Applet on
www.centralpoint.nl. It appears here as a light-green rectangle saying
"Loading...".

I think this might have security implications: basically we're allowing one
site to overwrite content of another site displayed on a different tab. The
user will think the content comes from a different source than it actually
does.
