Subject: xcb: Fix getting the window types from the property of QWindow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

wm_window_type_property_id is a dynamic property, so we should
check that it is set by using QObject::dynamicPropertyNames()
instead of QMetaObject::indexOfProperty().
