Timeline animation doesn't start automatically when Qul item instantiated before Qul::Application

Reproducible project attached.
TimelineAnimation is enabled at qml, but the animation doesn't start automatically.

Timeline animation doesn't work with following entrypoint code.

Qul::initHardware();
Qul::initPlatform();
static MainScreen item;
Qul::Application app;
app.setRootItem(&item);
app.exec();

Qul::Application is needed to declare before Qul item.
