In a qml file when you write a function documentation like:

\qmlmethod string TextArea::getFormattedText(int start, int end)

You would expect the return type "string" to be printed in the method description (this is the case when qmlmethod is used in a cpp file)

However, this is not the case.

See the current TextArea::getFormattedText documentation:
