No autocompleting for Qt3D modules importing

If I use qt-creator and start a new empty qt quick project, add the line

QT += 3dcore 3drender 3dinput 3dlogic 3dextras qml quick 3dquick 3danimation

 to the .pro file, then try importing a module like:

import Qt3D.

And hit ctrl+space at this point, the possible modules don't show up.
