  1. Agree, we could cache the last mouse/tap position, so when calling chart.update():

    if tooltip visible {
  if data intersect {
    update toolip
  } else {
    hide tooltip
  }
}

  3. This is just annoying me, simple solution: revert back to chart.js@2.7.0 there it works. I don’t know why this receives no priority, I don’t have the experience myself to do a PR, otherwise I would.
