I just discovered that in the Menu Manager the Action for selecting media files or other contant seems broken for me.
(Content → Menu Manager → Create Menu → Media/Content)
After looking into the code I found that the js function inside modules/contentbox/modules/contentbox-admin/views/menus/providers/media/adminHelper.cfm should trigger a popup which did not work for me.
I tested this in Firefox 109.0.1 (64-Bit) and Google Chrome 109.0.5414.119 (x86_64).
I noticed that when injecting the on-click function via the browser console and placing the args.xehMediaSelector variable manually everything works like it should, which suggestes that the eventListener just wont trigger.
This bug also affects the “content” option for menu Items (modules/contentbox/modules/contentbox-admin/views/menus/providers/content/adminHelper.cfm).
