Source of example is being opened with license header expanded

1. Install a Qt package.
2. Start the Creator from the package with an empty settings directory.
3. Go to Welcome mode, "Examples" tab.
4. Click "Application Example".
5. Click "Configure Project" or go to Edit mode.
   main.cpp is shown with expanded license header, so all you see is the header.

AFAIK, the file should be opened with collapsed license header. When opening further files, this works correctly.
