Do not highlighting registered property in editor

This bug appeared 76547654867867654 times in Qt creator. One update all is OK another one - not working. Could you make it stable??? I am using enterprise version of QT Creator.

Just updated and again do not highlight and code complete in QML of registered element in C++.

I have in C++:

oEngine.rootContext()->setContextProperty("ASkin",oBackend->pUIHandler->pSkin);

But in editor nothing! See screenshot.

In application all is working properly. The issue is bout Qt Creator only.

All of it is really making developing process very complicated! Especially if developer not experienced enough.
