Ah. See the FIXME in the test:
;; FIXME: There are twice as many inner
;; definitions as expected due to Bug#42701.
;; Once that bug is fixed, remove the duplicates.
Bug#42701 still isn't fixed, but the fix to bug#48489 has "suppressed"
its symptom in this case. We can therefore resolve this FIXME.
However, then the edebug-tests-duplicate-symbol-backtrack doesn't
really test any more what it should be testing. So I'll see that I can
change it to restore the previous behavior (which requires
backtracking and overlapping &or branches).
