I haven't tested this in a while, so I might be misremembering, but
Gecko has magic to rewrite all JavaScript references to the old
document to point to the new document.  I don't know whether that
magic is required by web compatibility, but I bet it is and I don't
think we want to introduce more of that magic into WebKit.  (We do
something similar for Window today, but Window is a unique snowflake.)
