Qt Design Studio has wrongly configured examples-manifest.xml

Qt Design Studio generates examples-manifest.xml with unexpected url entries.
Examples docUrl and imageUrl in generated manifest start with qthelp://// and then just proceeds with the file path relative to manifest file, for example:

docUrl="qthelp:////qt-design-studio-coffeemachine-example.html"
imageUrl="qthelp:////images/coffee-machine-overview.png"

QDS examples-manifest.xml was never used, so we never had issues with it, but now we are using qtcreators settings Help/InstalledExamples property and Qt Creator has issues locating documentation for them.
Manifest has to create entries with property values referring to registered documentation, like these:

docUrl="qthelp://org.qt-project.qtdesignstudio.200/doc/qt-design-studio-coffeemachine-example.html"
imageUrl="qthelp://org.qt-project.qtdesignstudio.200/doc/images/coffee-machine-overview.png"
