AFAICT, we don't support autoreverting symlinks, since Dec 2013, so it
sounds strange that you say it worked in Emacs 27.
The relevant discussion is here:
https://lists.gnu.org/archive/html/emacs-devel/2013-12/msg00282.html
The reason for this non-support seems to be performance.
I hope Michael (CC'ed) will be able to tell more about this.
A workaround is to set auto-revert-use-notify to nil.
