ObjectPicker doesn't work for a dynamically created entity if there isn't already another entity with ObjectPicker

if(!rootEntity_) return;

auto cuboidEntity = new Qt3DCore::QEntity(rootEntity_);
auto mat = new Qt3DExtras::QPhongMaterial(cuboidEntity);
mat->setDiffuse(QColor(217, 217, 255));

auto picker = new Qt3DRender::QObjectPicker(cuboidEntity);
connect(picker, &Qt3DRender::QObjectPicker::clicked, [=]{ qDebug() << "c++: clicked entity" << cuboidEntity; });
mesh->setXExtent(1);
mesh->setYExtent(1);

cuboidEntity->addComponent(mat);
