Memory leak in QSGFramebufferObjectNode

There's a memory leak when setting texture to QSGFramebufferObjectNode object in QQuickFramebufferObject::updatePaintNode() function defined in qtdeclarative/src/quick/items/qquickframebufferobject.cpp

n->setTexture(window()->createTextureFromId(displayTexture,
                            n->fbo->size(),
                            QQuickWindow::TextureHasAlphaChannel));

If QSGFramebufferObjectNode object already owns the texture that one is not released, causing memory leak.

QSGFramebufferObjectNode is managing the lifetime of the texture manually without using parent class QSGSimpleTextureNode::setOwnsTexture() function, as suggested by this code in its destructor:

~QSGFramebufferObjectNode()
{
    delete renderer;
    delete texture();   // << HERE
    delete fbo;
    delete msDisplayFbo;
}

Is there a reason why it does not make use of setOwnsTexture()?
