QDoc: Strange behaviour with QML submodule links

The following lines produce links to the subsections of http://qt-project.org/doc/qt-5/qtquick-releasenotes.html#qt-5-0-additional-qml-modules . I cannot figure out why this happens – this section of the Release Notes doesn't contain any bookmarks.

• \l {QtQuick::Particles}
• \l {QtQuick::LocalStorage}
• \l {QtQuick::Window}
• \l {QtQuick::XmlListModel}

In contrast, QDoc complains "warning: Can't link..." with these (as expected):

• \l {QtQuick::Controls}
• \l {QtQuick::Dialogs}
• \l {QtQuick::Layouts}

Also, this should produce a link to "Qt Quick Window QML Types" (http://qt-project.org/doc/qt-5/qtquick-window-qmlmodule.html), but QDoc complains "warning: Can't link...":

• \l {QtQuick.Window}

In contrast, these produce links to the various "Qt Quick ____ QML Types" pages (as expected):

• \l {QtQuick.Window::Window}

  (links to http://qt-project.org/doc/qt-5/qml-qtquick-window-window.html; shows that QDoc CAN resolve the "QtQuick.Window" module)

• \l {QtQuick.Controls}
• \l {QtQuick.Dialogs}
• \l {QtQuick.Layouts}
• \l {QtQuick.Particles}
• \l {QtQuick.LocalStorage}
• \l {QtQuick.XmlListModel}
