Updated thread notice has become too small, full list of avatars no longer showing on iPad

Additionally on iPad the full 5 avatars would show and now only one shows, making it more like an oversized mobile view.

I’ve just merged an adjustment that is less aggressive about hiding avatars on smaller screens, hopefully this helps!

UX: hide topic list views and posters less agressively on small screens
