+    // 1) Some page is loaded (for example QWebView::setUrl()) and loadFinished() signal
+    //    emitted, then view set right position inside page.

+    // 2) After this, page JS finishes it's work and change font settings (size).
+    //    This leads to contents "moving" inside view and as a result we have wrong position.

+    // Therefore secondly, we fix position after loading with using standard QWebFrame method
+    // scrollToAnchor() to avoid page reloading which happens if view's methods like
+    // load() or setUrl() are used.
