"There are no users matching '' error message appears after reloading the editor page

1. On initial load, the node author field has a value formatted like this: username (USER_ID)
2. After the first autosave, the field value becomes just the user id.
3. Now, when the form reloads (such as a refresh that uses autosave data) there is just a 2 in the field and when the validators are called as part of the build, \Drupal\Core\Entity\Element\EntityAutocomplete::validateEntityAutocomplete will call $match = static::matchEntityByTitle($handler, $input, $element, $form_state, !$autocreate); and there is no title to match, because $input is just the user ID, not the name.

I suspect this will be addressed if we address the process that converts the field value from username (USER_ID) to just the id.

MR has a few bits that are necessary to get this working, but nothing touching on comment #2 yet. Some way of calling EntityAutocomplete::valueCallback or doing the equivalent will likely be needed.

@tedbow ran into what is likely this issue and narrowed it down to the changes made in 📌 Media Library dialogs triggered from page data do not have buttons yet Active

The work done so far in the MR is probably worth keeping, even though they were not related to #3506467 (autocomplete should be adding value, not label, and details contents should be in the DOM).

The parts still not working are probabl related to the #3506467 changes so now we have a place to target our efforts

The not-yet-addressed part of this is addressed by 📌 Get Options as buttons in Page Data form working Active , so that should be prioritized

This blocks ✨ [PP-1] Make link widget autocomplete work (for uri and uri-reference props) Postponed .

#6: #3515294 is in now :)

Attempted to fix the failing tests.
One was a legitimate regression in details elements. Went with a CSS solution instead of using the hidden attribute

Needs @bnjmnm's final sign-off.
