Summary of Changes
The onchange event is not triggered on a form element when the element's value is updated programmatically, only on user input, therefore a "change" event must be dispatched when the user id field value is set.
Without dispatching a change event, the change event listener created for the data-onchange attribute is not triggered, and the associated function is not called.
Testing Instructions
Edit administrator/components/com_content/forms/article.xml and set an onchange attribute for the create_by field, eg:
<field
name="created_by"
type="user"
label="COM_CONTENT_FIELD_CREATED_BY_LABEL"
onchange="(function(){console.log('change')})()"
/>Create or edit an article, and in the Options tab, select a new user for the Created By field.
Expected result
In the browser console, "change" should be displayed when the new user is selected.
Actual result
Nothing is displayed in the console as a change event is not triggered.
Documentation Changes Required
None.

I have tested this item
Hints for other testers:
- It needs to run npm to "compile" the changed js.
- I had to force reload the page in order to get rid of cached js.
No idea why this change got lost.

Obviously got lost at some point in merge conflicts - thankyou!
This has already been proposed, tested and merged - #21323 - but seems to have been dropped at some stage.
