        REGRESSION (r79953): Can't type in MS Outlook 2011
        https://bugs.webkit.org/show_bug.cgi?id=56665

        Restore the expected result before r79953. r79953 changed behavior slightly in function
        finishedLoadingWithDataSource in file mac/WebView/WebHTMLRepresentation.mm, where
        core(webFrame)->editor()->applyEditingStyleToBodyElement() was called but not before r79953
        or after this patch.

        r79953 removed the WebView level editablity which is persistent no matter whether
        underlying document itself is changed and editability gets lost. The resolution is to
        set this WebView editable value to WebCore. This avoids the callback from WebCore to
        WebKit which was the main goal in r79953 to improve performance.
