Fields hidden after form error

Created on 21 February 2025, about 2 months ago

When form validation fails after form submission (not when ajax catches the error) new values may be hidden.

Starting with a default install of drupal and this module installed
Create 4 terms in the Tags vocabulary
Modify the article content type to make the body field mandatory and the tag field to be limited to 4 values
Create a new article
Fill in mandatory fields, add 3 values to the tag field, DO NOT fill in the body field
Submit the form
See the error about the missing body field
See that the tag field is not displaying the second and third value that was filled in

Some extra checks during the form alter is required in order to detect user input that is not yet part of the form state or the field item.

Thanks for contributing the fix. Can we also add a test to prevent this won't regress in the future?
Thanks!
