Press "background" on the demo page to add a fixed background.
The background image to its own layer, which can be seen if you show composited borders, however nothing appears in the layer list for the page.
I guess this is because the background image gets its own layer, rather than the element with the background image getting a layer.

According to Simon Fraser, fixed backgrounds don't generate a RenderLayer, but rather a special GraphicsLayer directly attached to the root layer's RenderLayerBacking. As such, we'd need special code in the inspector to know how to deal with this, and how to generate a Layer object for a GraphicsLayer vs. a RenderLayer.
