(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
The test case here isn't complete, so I can't test whether the problem
is still present. I think it might have been fixed by:
commit 4bd7963e2e244ace94afa59124f2637543d74ba2

(add-hook, remove-hook): Fix leaks (bug#48666)
* lisp/subr.el (add-hook, remove-hook): Rewrite the hook depth
management so we only keep the info relevant to functions present on
the hook.
Do you still see this problem in Emacs 29?
