No F1 help for Qt and QtObject elements

Create new QML app project. Place your cursor over the "Qt" in the supplied "Qt.quit()" statement. Press F1. You get "no documentation available". Whoops.

But actually, documentation is available: place your cursor on "Rectangle" instead, press F1, click on "QML elements", click on "Q", then you see QML:Qt and QML:QtObject.
