This example causes the tab to crash:

<!DOCTYPE html>
<html>
<body>
  <canvas id="myCanvas" width="200" height="100"></canvas>

  <script>
    var canvas = document.getElementById("myCanvas");
    var ctx = canvas.getContext("2d");
    ctx.font = "30px -apple-system";
    ctx.fillText("⚪ Grey - On hold",10,50);
  </script>
</body>
</html>
