ShaderEffectSource does not stack with layer.effect

If an effect is assigned to an item as a layer.effect and this item is used as a shader source the layer.effect is not rendered in Qt 5.10. |
See the attached example and screenshot for details.

The screenshot is done with Qt 5.9. In the screenshot, the Glow and FastBlur effect is rendered even if rendered indirectly as a ShaderSource.
The colorize effect was not rendered indirectly even in Qt 5.9.

Why this looks like a weird corner case, the Qt Quick Designer uses rendering to texture to render all items.
This means that with Qt 5.10 layer.effects are not visible in the WYSIWYG editor.
