    // Fixes for correct positioning. The problem looks like the following:

    // 1) Some page is loaded and loadFinished() signal is emitted,
    //    after this QWebView set right position inside page.
    //
    // 2) After loadFinished() emitting, page JS code finishes it's work and changes
    //    font settings (size). This leads to page contents "moving" inside view widget
    //    and as a result we have wrong position.
    //
    // Such behavior occurs for example with QtHelp pages.
    //
    // To fix the problem, first, we disable view painter updates during load to avoid content
    // "flickering" and also to hide font size "jumping". Secondly, we reset position inside page
    // after loading with using standard QWebFrame method scrollToAnchor().
