This MOD is called “YouTube banner modal”
It USES this JQUERY SLIM VERSION
The external script asset can completely destroy a lot of JQuery-functions, IF another (full) Jquery Version is already loaded on the same page.
THUS: I suggest anyMod might print a warning to the console, IF TWO or more Jquery-Libaries are found loaded on the same page.
This error is hard to track down.
The error can be especially confusing and unexpected.
The warning-message printed to the console would be most helpful if if stated the whereabouts of all Jquery Libaries at play.
The warning message may let the admin know which MODs are loading a second jquery asset .
