paintEngine has no documentation

The method QWidget::paintEngine has some documentation in C++ (http://doc.qt.io/qt-5/qwidget.html#paintEngine), but strictly none in Python (it is not even in the table of contents: https://doc.qt.io/qtforpython/PySide2/QtWidgets/QWidget.html).

In the WebXML output, the method is present, though without any text:

{{ <function threadsafety="unspecified" name="paintEngine" fullname="QWidget::paintEngine" href="qwidget.html#paintEngine" status="active" access="public" location="qwidget.h" filepath="C:/Qt/5.11.1/msvc2017_64/include\QtWidgets/qwidget.h" lineno="581" virtual="virtual" meta="plain" const="true" static="false" overload="false" delete="false" default="false" final="false" override="true" type="QPaintEngine *" signature="QPaintEngine * paintEngine() const override">}}
