If someone is in a similar situation to mine and looking for a solution...I discovered that I needed to add a tabindex attribute before my div could gain focus():

featured.setAttribute('tabindex', '0');
featured.focus();
console.log(document.activeElement === featured); // true

(I came across this helpful answer here: Make div element receive focus)

And remember, ensure the body element is fully loaded before giving focus to a child element.

Make sure to position the input element before the JavaScript code or wait for the page to fully load before triggering your JavaScript function. This will ensure that it runs correctly.

For example:

<input type="text" id="test" />
<script type="text/javascript">
  document.getElementById("test").focus();
</script>

If you are using jQuery, you can utilize the .ready() method to execute your code only after the DOM has fully loaded:

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
  $(document).ready(function () {
    $("#test").focus();
    // document.getElementById("test").focus();
  });
</script>

I encountered a similar issue as well. The solution that worked for me was to wrap the code in a setTimeout function.

function focusOnSearchField() {
    // Delay setting the focus on the text field
    setTimeout(function() { jQuery('#searchTF').focus() }, 20);
    // Continue with your tasks...
}

Experiencing a similar issue to what Martin Buberl shared earlier, where the element was not present at the time I called focus(). To overcome this, I utilized window.requestAnimationFrame() to schedule a callback that will set focus in the next rendering cycle.

window.requestAnimationFrame(() => elm.focus())

Make sure to enclose it within a document ready function and confirm that jQuery is included in the file.

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    <script>
       $(document).ready(function() {
          $("#test").focus();
       });
