Two Wikimedia users testing Maniphest were confused by clicking "Edit" on their own existing comment and instead seeing a new "Edited" comment added while the previous comment was not "replaced", so there seems to be a mismatch between the wording and the expectation.

Hmm, how do I find out how old a Phab checkout is (in this case the one on wmflabs.org)? Any way I can see a revision ID?

If you're an administrator, you can check /config/all/ on your install, you should see a string like this at the top:
Phabricator Version 47245b1b59c7523af8f442ba05ffb4a4a8b41991

(D8702 should have fixed this, so my guess is that you're just a little bit out of date, but if it reproduces on this install we might not have nailed it completely.)
