Autocomplete doesn't trigger `formUpdated`

The information needed to work on this has not been provided, as explained in #20. It now time to close this issue.

If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue → (starting from "Install Drupal core").

This issue is still happening, I have added steps to reproduce it.

The issue was able to replicate on the Drupal 11.x version. I tried to reroll the patches #14 and #17. The reroll is not resolve the issue.

I tried the below options but still no luck,

1. Triggering autocomplete element on selectHandler()
$(event.target).closest('form').trigger('formUpdated');

2. Triggering parent form on selectHandler()
$(event.target).closest('form').trigger('formUpdated');

3. Bind event on Drupal.behaviors.autocomplete attach

$autocomplete.on('focusout', () => {
            $(context).trigger('formUpdated');
          });

Non of the above method helped.
