applied patch #4 to Drupal 10.5.1

thanks for the patch!
please release!

+1 for RTBC.
Couple of more issues that you might be facing with 10.5+/11.2+ (CKEditor 45+ support)

Also, see the following patches for another modules with similar issues:

• 🐛 Uncaught CKEditorError: Cannot convert undefined or null to object Active
• 🐛 D11.2: Uncaught CKEditorError: Cannot read properties of undefined (reading 'viewUid') Active

Thank you all for your work here!

The issue is not really related to jquery.once because the once functions used by the modules are those provided by CKEditor.
The issue was that CKEditor made a breaking change in their internal. See 🐛 Update drupalFile.js for compatibility with the latest CKEditor version Active .
