The buggy behavior results from navigating back/forward to a WebHTMLView that's
already been -close'd. This problem has existed prior to r17871, but clearing
the private data (in particular, the data source) made it more evident. What
I've seen is that -[WebHTMLView close] is called from +[WebHistoryItem
_closeObjectsInPendingPageCaches], but the WebFrame has its own WebHistoryItem
which holds a pageCache which references the now-closed WebHTMLView. When you
navigate back/forward, the WebHTMLView is pulled from there and reused despite
having been closed.
