QML doesn't requests second texture from the image provider

Hello,
We have found a strange behavior while streaming from the Qt 3D studio to QML Using Texture type in QQuickImageProvider.

Steps:
1. Add two layers to the 3DStudio presentation
2. Add two images which must represent these layers in QML

Image {
            id: layer_persp
            width: root.width / 2
            height: root.height
            source: "image://3ds/Scene.First"
}
Image {
            id: layer_ortho
            x: root.width / 2
            width: root.width / 2
            height: root.height
            source: "image://3ds/Scene.Second"
}

3. Using Image provider from the sample application in attachment fetch texture id's from the 3DStudio render engine.

Expected result:
Both layers renderers correct

Actual result:
Only one layer visible and duplicated on both Image objects.
But if any event will be triggered or any other element will become visible the second image will fetch the second layer.
Also, we have noticed QML doesn't try to bind the second texture at all before the events.
