Strange pages being generated for TestCase and SignalSpy QML types

It looks like QDoc is trying to generate C++ pages for the TestCase and SignalSpy types.

• They are listed on the "All Classes" page: http://doc-snapshot.qt-project.org/qt5-dev/qtdoc/classes.html
• There are collision pages, but both have the same HTML filename:
  • http://doc-snapshot.qt-project.org/qt5-dev/qtquick/collision-testcase.html
  • http://doc-snapshot.qt-project.org/qt5-dev/qtquick/collision-signalspy.html
• In Qt 5.1, they had different filenames:
  • http://qt-project.org/doc/qt-5.1/qtquick/collision-testcase.html
  • http://qt-project.org/doc/qt-5.1/qtquick/collision-signalspy.html

By the way, I'm wondering why are these types are in Qt Quick and not Qt Test...?
