A model menu that stays on the phone

Inside a chat the picker sits mid-bar with the panel buttons to its right,
and its menu opened from the picker's right edge -- at 390px it spanned
x = -132..226, cutting every model's name off. Below 48rem the bar is now
the containing block and the menu is pinned between its edges (capped at
24rem). Opening it on a touchscreen no longer focuses the filter, which
raised the keyboard over half the list.
