iOS 13.4 / 13.5 / 13.5.1 : pointer (pointerup) events missing

Question

I made a simple HTML page in which I listen to the pointerup event (each triggered event displays a log on the page).

CodePen link : https://codepen.io/rlebosse/pen/JjGYqRV

Since iOS 13.4 (13.5 / 13.5.1 too), when I double tap on the page, there is only ONE "pointerup" log displayed. I tried using a real device (iPhone XR / iPhone 11 Simulator).

When I double tap, there is a "pointerup" event that is missing, thus not catched.

With a iPhone 11 Simulator with iOS 13.3, I have the right amount of "pointerup" events : two (first and second tap).

Can you help me with this issue ? Is there a way to make both being catched ?

Thanks in advance !

The code :

<body>
  <head>
    <title>Test</title>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    <style>
      p {
        padding: 0;
        margin: 0;
      }
    </style>
  </head>

  <body>
    <div id="observing-events-log" class="log">
      <strong>Objects events</strong>
    </div>

    <script type="text/javascript">
      function logObservingEvent(eventName) {
        var el = document.getElementById("observing-events-log");
        var para = document.createElement("p");
        para.appendChild(document.createTextNode(eventName));
        el.appendChild(para);
      }
      document.body.addEventListener('pointerup', (ev) => {
        logObservingEvent("pointerup");
      })
    </script>
  </body>
</body>
