Q: popstate does not work since safari 16? It was working until safari 15 I would like to display an image when the user clicks the back button of the browser.
The code below worked fine in safari 15.5, but when I upgraded to safari 16.1, it did not work.
Popstate not working in safari 16.1?
<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <script>
      history.replaceState(null, null, null)
      history.pushState(null, null, null);
      window.addEventListener('popstate', function () {
        alert('fired');
      });
    </script>
  </head>
  <body>test</body>
</html>


I confirmed that when I clicked the browser back button in safari 15, the alert message was displayed.
When I ran it in safari 16, nothing was executed and the previous page was displayed as is.

A: In my case, I had some async scripts in HTML and some browser abilities were blocked until those scripts loaded completely.
