In Drupal 11.2 and 10.4, the 'Select Media Source' field disables itself opposite to what it should be. This error is shown by a failing test.
Because unchecking a media item could force you to reload the image selection, we've removed the feature with 1.1.0
This issue is a placeholder to bring back that feature in a future release of Acquia DAM.
With 1.1.0-rc1 (on Drupal 11.2 or 10.4):
Edit a piece of content with the media library widget enabled for ckeditor
Open up the media library from ckeditor
Choose any media item.
You'll notice the other items are greyed out, but the 'Select Media Source' dropdown isn't.
Unselect the media item you checked.
You'll notice the 'Select Media Source' dropdown now is greyed out.
Fix the JS to work with both newer versions of Drupal and legacy versions as well.

The feature has been removed from 1.1. I added back the feature as an MR in this issue and marked NW to be worked on in the future.
