I currently have the issue in one XWiki 17.10.4 envionment, that for users without programming rights, the navigation tree hangs with a “Loading” spinner and the notification icon in the upper right isn’t placed correctly.

A similar issue reported without any solution: Navigation Bar for Users for with reading access
Navigation Panel rights also seem to be ok:
