+    //
+    // 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().
