Can't build QT6 WebEngine example

This is a regression of https://bugreports.qt.io/browse/QTVSADDINBUG-951
From what I can see module names for both QT5 and QT6 are being added to the project.

core;opengl;network;gui;widgets;qml;positioning;printsupport;webchannel;quick;webengine;webenginewidgets;webenginecore;webenginequick
