jQuery updating ancestor content when nested element is removed

I am using jQuery 3.6

I am deleting a nested element from a portion of my page, and I want that section of the page to automatically update, to reflect the change - I was expecting the browser to automatically update the modified section, but it doesn't and the change is only visible when I refresh the page.

Here is a snippet of the HTML:

 <div id="foo" class="row text-center text-lg-left">

    <div class="col-lg-3 col-md-4 col-6">
      <a id="abc-1"><img src="image1"></a>
    </div>

    <div class="col-lg-3 col-md-4 col-6">
      <a id="abc-2"><img src="image2"></a>
    </div>

    <!-- etc -->

</div>

Here is my Javascript snippet:

 $.ajax({
                type: 'post',
                url: "/path/to/post/to",
                data: {'identifier': $(this).attr('id'), 'status':1, 'csrfmiddlewaretoken': '1234567abc'},,
                success: function(data) {
                   /* assume we have variable named 'identifier' ... */
                   $(`a#${identifier}`).parent().remove();
                   
                   /* next two lines is a brute-force attempt to
                      force the element to update - but it still
                      doesn't update, until I refresh the page!
                   */
                   let remaining_content = $('div#foo').html()
                   $('div#foo').html(remaining_content);
                },
                error: function(xhr, status, error) {
                  var err = JSON.parse(xhr.responseText);
                  alert(status);
                  alert(error);
                  alert(err.Message);
                }    
});

How do I get the div with id foo to update (ideally with some nice color fade-in/out) when it's content changes (deletion of elements in this case) - without having to refresh the browser to observe the change?
