Pills only with the controls, web links in their final layout at once, chat pop-ups when paused by default

- Next episode (known ending, else the last two minutes) and Skip ED
  show only while the controls are up, like Skip 1:30 (PillGate).
- A web link's name and wide cover slot show from the first state, so
  nothing flips when its thumbnail arrives.
- Chat pop-ups default to Only when paused.
