Take the jolt-native that can scroll a backlog and paint a reaction

Three revs of it, and every one is the terminal backend:

  a7852016  the wheel goes to the list under the pointer rather than to
            the first one painted — which on a wide screen is the chats
            sidebar, so the conversation would not move; it reads where
            the list is from what was remembered rather than from a prop
            the caller clears on every render; a notch is three rows;
            and page-up and page-down exist

  dce285fb  `:reaction` and `:emoji` are tags. They were unknown, and an
            unknown leaf paints its label, which a reaction has not got —
            so every chip and pill was nought columns wide and took no
            clicks: no way to react in a terminal, to answer, to edit, or
            to see that anybody else had. The grid learned that an emoji
            is two columns, without which a click lands a cell off from
            there to the right edge

  3dd441e7  a cell holds the whole glyph, selector and all, and a scroll
            copies cells rather than characters — a reply arrow drawn as
            the small mono arrow was the selector being dropped, and the
            backlog is the one place that copy happens
