It appears to be caused by any list item element inside of a running element.
Minimum reproducible example:

<style>
  @page {
    @top-center {
      content: element(header);
      width: 100%;
    }
  }
</style>
<div style="position: running(header);">
  <ul>
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
  </ul>
</div>

Just ran into the same error message. Will try to narrow down to a minimal repro and report back...

Hey there,

here is a repro - in my case the error seems to be related to a absolute positioned element in the running header. Once I change the .logo position to something else it renders fine:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <style>
        header {
            position: running(header);
        }

        @page {

            @top-center {
                content: element(header);
            }
        }


        .logo {
            position: absolute;
            top: 0;
            right: 0;
        }
    </style>
</head>

<body>

    <header>
        <div class="logo">
        </div>
    </header>

    <h1>My title</h1>

</body>

</html>

Duplicate of #1540, as list markers are absolutely positioned.
