[FIXED] Various minor issues

  - Typing :+1: doesn't replace the short code with the thumbs-up emoji
  - Moving the mouse over the emoji complete panel highlights the wrong emoji when mScrollPos > 0
  - Emoji complete panel is missing attributes
  - Crash when attempting to show the tooltip for an emoji text segment
  - Emoji autocomplete panel can sometimes show empty (type ':cat', select the heart eyed one, Ctrl-Z and then type 2 which should show the emoji for :cat2 but shows an empty square instead)
