"When accessing the browser's window and document objects from JSNI,
you must reference them as $wnd and $doc, respectively. Your compiled
script runs in a nested frame, and $wnd and $doc are automatically
initialized to correctly refer to the host page's window and
document."
'document' above references the iframe's document where your code runs
(i.e. the *.cache.html).
