DOMPurify is not attached to the proper librarie and may end undefined.

Automatically closed - issue fixed for 2 weeks with no activity.

I'll just leave a note here that Admin Toolbar → stopped working for me, and there was a "Uncaught ReferenceError: DOMPurify is not defined" error in the Console. Uninstalling the Search Autocomplete module fixed the problem, and the dropdowns worked again.

Uncaught ReferenceError: DOMPurify is not defined

"/libraries/dompurify/dist/purify.min.js?v=10.2.2"
is loaded after
"/modules/contrib/search_autocomplete/js/jquery.autocomplete.js?v=10.2.2"

The module page does not say so but ensure that the library is in the libraries folder via the path /libraries/dompurify/
You can download the library from github https://github.com/cure53/DOMPurify
change the name of the folder to "dompurify"
