AJAX error when editing term content

@VladimirAus Sorry for the late response. Here is the requested information:

Version of my environment:
Drupal 9.5.2
PHP 8.0.27
Taxonomy Manager version 2.0.7 and 2.0.8

Steps to reproduce:

1. Go to Structure > Taxonomy and edit any vocabulary.
2. In the Manage fields tab, add general field like (Email) or (Link)
3. In the new field setting, select Unlimited, save field settings then save settings. This will add the Add another item button
4. Navigate to the list tab and add some terms to your vocabulary
5. Go to Structure > Taxonomy Manager and click on that vocabulary. From the terms list block on the left, click on any term. This will open the edit panel to the right.
6. Scroll down to the field you added and click on the Add another item. A spinning (Please wait) will show momentarily and then disappear without adding another field.

Please see the attached screenshot.

@VladimirAus Did you have the chance to look into the information I provided?

hi all
i also confirm this issue after selecting "Entity browser" as Widget on field's form display and now going back to the edit/add term page

Please create MR.

I also have the same scenario as @delacosta456 and have confirmed that it is happening.

It looks like it's related to the Drupal core issue https://www.drupal.org/project/drupal/issues/2504115 → .

The workaround is to render the form without Ajax and send a taxonomy term ID through the URL query parameter.
The patch is attached.

Thank you for your contribution.
Can you create MR?

@dburiak, I pushed your patch to the branch. Please fix the issues we found while testing the latest changes.

The PR is updated.
The updated patch can be found in the attachment.

I had to make a small adjustment to this patch since it did not apply cleanly due to another taxonomy manager patch 🐛 Form element taxonomy_manager_tree broken RTBC that I had to apply earlier. Here is an updated patch just in case there are folks out that applied patch from issue 3474919.
