Exactly.  I think we need to fix this problem.  It really should work.

All functions advised with a non-:around advice have such
a "recognizable wrapper"; and that's indeed what
advice--called-interactively-skip checks in

          (and (eq (nth 1 frame2) 'apply)
               (progn
                 (funcall get-next-frame)
                 (advice--p (indirect-function (nth 1 frame2)))))

IOW the nadvice.el machinery is itself the recognizable wrapper.
Not sure why this fails in your test case, tho.

For :around advices, the machinery does not provide a recognizable
wrapper, so we might want to add an ad-hoc wrapper like you suggest for
those cases, tho maybe we can avoid the cost of such a wrapper, by
keeping the so-advised inner-functions in a hash-table (so we can still
recognize them, even tho they're not tagged directly in the backtrace).

So, I think the first thing is to figure out why your test case fails.
