tooltip on chart.stop() will no longer be displayed

[A B (Takumi Lee)]

Hi,
First of all I would like to thank you for this very good JS librar :)

My current concern is to pause the stream, which I found.
var isRunning = true
document.getElementById("button").onclick = function () {
  if (isRunning) chart.stop()
  else chart.start()
  isRunning = !isRunning
}

After pausing, I want to view the signal with the tooltip. Unfortunately, it doesn't work :(

Best regards
Aaron
