Hi, could someone to help me ?
I have faced with an exception when HtmlUnit (WebDriver) parse HTML page that contains such code

<script>
    const forms = document.getElementsByTagName('form');
    for (const form of forms) {
        form.addEventListener('submit', preventDoubleClick);
    }
    function preventDoubleClick({ submitter }) {
        if (submitter) {
            submitter.disabled = true;
        }
    }
</script>

Stacktrace

Does it because Rhino do not support for...of loop ?
Is there any way to fix it (without rewriting loop 😄 )?

Thanks
