Problem/Motivation
In Drupal 10.3.2 or 10.3.3, while authoring a Media field referencing the Remote Video media type with the Media Library widget as a non-administrator, I'm unable to add a URL. This is true for both content types and taxonomy terms.
As an administrator, I can add a URL in this way.
As any role with permission to create Remote Video media, I can add a URL and create a media entity via /media/add/remote_video, then add it via the media library list in the widget. So there is currently a workaround.
In attempting to debug the issue, I noticed that in core/modules/media_library/src/Form/OEmbedForm.php, when I remove the #required attribute for the url field, I am able to select "Add" but the saved entity has an empty URL.
Steps to reproduce
1. Add field to content type or taxonomy:
Entity reference
Reference type: Media
Media type: Remote video (allowed providers: YouTube, Vimeo)
2. While logged in as a non-administrator, author content or taxonomy term. Select "Add media".
3. In the Media Library widget, enter a valid YouTube or Vimeo URL and select "Add".
4. The URL field becomes blank. Error messages related to required field missing value appear (see attached screenshot).
