84806 - After purging session history, web nav events aren't properly reset

Status: VERIFIED WONTFIX

(Core Graveyard :: Embedding: APIs, defect)

1. Make sure that session history listener has been added in the test framework.
In mfcEmbed, I added:
nsWeakPtr weakling(
        dont_AddRef(NS_GetWeakReference(NS_STATIC_CAST(nsISHistoryListener*,
mBrowserImpl))));
	rv = qaWebBrowser->AddWebBrowserListener(weakling, NS_GET_IID(nsISHistoryListener));

2. Enter at least one url to create a session history.
3. Purge session history. In mfcEmbed:
  nsCOMPtr<nsISHistory> theSessionHistory;
  mWebNav->GetSessionHistory( getter_AddRefs(theSessionHistory));
  rv = theSessionHistory->GetCount(&numEntries);
  rv = theSessionHistory->PurgeHistory(numEntries);
4. Notice that the back and forward buttons are disabled. That's fine at this
point. Now, enter another url.
Result: The session history events are disabled (forward, back, reload, etc.)
Expected: Since we've entered a url, they should be enabled.
Note: They get enabled after entering the Second url.

Myself and depstein talked about it. THis is due to the way pages are added to 
SH. Fixing this will bring up another bug. I think it is not a serious flaw in 
the way PurgeHistory works.
