Peeking cards is at the bottom for fully rendered NTP on initial load, Peter will look at the 2nd snap point peg to the bottom

I just looked at the latest build. What's remaining here?

When we can't see Most Likely fully when scrolled to the top, we add Most Likely as a 3rd snap point.

When we have snapped to this snap point, the peeking card isn't necessarily in the correct position (we're getting lucky at the moment and it looks about right by chance).
