title: 3-fingers Multi-Touch Support in Web Apps
body: <p>Is it possible to handle more than 2-finger touch events in Javascript? In my tests, events stop firing when a third finger is added. I created an example using jQuery and the official jQuery Plugin: Pointer Events Polyfill. Tested in Chrome and Microsoft Edge on Windows 10 Professional using a Wacom Cintiq 22HD Touch Monitor.</p>

  <pre><code>(function ($) {
      var pointers = [];
  
      $('#pointerTarget').on('pointerdown pointerover pointerenter', function (event) {
          var id = event.originalEvent.pointerId;
          if (!pointers[id]) {
              pointers[id] = $(`&lt;div id="${id}"&gt;&lt;p&gt;pointerId: ${id}&lt;/p&gt;&lt;/div&gt;`).appendTo('body');
          }
      });
  
      $('#pointerTarget').on('pointerup pointerout pointerleave', function (event) {
          var id = event.originalEvent.pointerId;
          if (pointers[id]) {
              pointers[id].remove();
              pointers.splice(id, 1);
          }
      });
  })(jQuery);
