Goal is to extract the text "Filter A" from the following ComputedStyle ...

    console.log(filters[0]);
    <td class="name" id="l:rcmrow0">
        ::before
        "Filter A"
    </td>
//
console.log(window.getComputedStyle(filters[0], ':before').getPropertyValue('content'));
console.log(window.getComputedStyle(filters[0], ':before').content);
//
var styles = getComputedStyle(filters[0], ':before');
console.log(styles.getPropertyValue('content'));
console.log(styles['content']);

All console.log outputs display "[]".

Please offer guidance on how to extract the pseudo element's text content.
