Problem/Motivation
When trying to edit a Paragraph in the material type
and save the node, after clicking the Save button nothing happens, an error appears in the browser console:
An invalid form control with name='field_paragraph[0][subform][field_first_column][0][subform][field_text][0][format]' is not focusable. <select class="js-filter-list form-select required" data-drupal-selector="edit-field-paragraph-0-subform-field-first-column-0-subform-field-text-0-format" id="edit-field-paragraph-0-subform-field-first-column-0-subform-field-text-0-format--wIGei0a2LSw" name="field_paragraph[0][subform][field_first_column][0][subform][field_text][0][format]" required="required" aria-required="true">…</select>
Steps to reproduce
Edit the Paragraph (the "Edit" button) and change the link in the First column, then click the "Save" button.
I checked all the fields for Paragraphs, all the checkboxes for "Required field" are unchecked.
The error appeared recently, most likely after some Drupal update, about a month ago there was no such problem.
