Misc · Asking and learning: Submit never rests; radio labels wrap

Survey's Submit asks for any missing answer instead of resting, so no
untick takes its focus handle out of the tree. Flashcards turn and go
round, and a quiz pick clears its ask, through methods the tests reach;
the poll's rows show which one holds the vote. forms::Radio's label
wraps in its own block, as Checkbox's does, so a long one stays in a
narrow box.
