   I can confirm this is still the case; here's with a different seed, and with GHC 8.10.4:

   hourMinuteFormat
     extended:                                                               FAIL (0.05s)
       *** Failed! "00:01": expected Just 00:00:60, found Just 00:01:00 (after 95 tests and 2 shrinks):
       00:00:60
       Use --quickcheck-replay=502299 to reproduce.

   Here is an exact, pinned reproducer:
