            This is just an invisible placeholder put in place so that the parent keeps its height
            stable as the RecyclerView updates from 0 items to N items. Keeping it stable allows the
            layout logic to keep the size of the preview container stable as well, which bodes well
            for setting up the SurfaceView for remote rendering without changing its size after the
            content is loaded into the RecyclerView.

            It's critical for any TextViews inside the included layout to have text.
