Merge branch 'emoji-optimizations' into shigusegubu

* emoji-optimizations:
  eslint
  fixed emoji picker showing up beyond viewport
  start loading emoji when picker is open
  remove the "textbox grows the 'wrong' way" behavior, replace it with more conditions to scroll to bottom
  arbitrary limit with option to overcome it
  emoji picker gradual render
  moved emoji stuff away from after-store and into users module since we only need emoji after login
