[MR UI] Make paper-items the only selectable elements in cast modes list

Currently when you are tabbing through the cast mode selection view in the MR
dialog, you cannot highlight the casting options, because the "Share your
screen" text gets selected instead (which doesn't change its appearance when
selected). It's not clear where the selection went, or that you can then
highlight the cast modes by pressing up/down arrow keys. This change makes
only the cast modes selectable.
