Forgot:
2-bis) Revert to the revision in question

That was at
http://commons.wikimedia.beta.wmflabs.org/wiki/Commons:Photo_challenge
http://commons.wikimedia.beta.wmflabs.org/wiki/Special:PageTranslation

Now tried:

4. Revert to preceding revision
5. Mark for translation: impossible because the "mark" link doesn't appear, but for some reason "This page contains changes which are not marked for translation." is now centred at the top. O_o

P.s.: The page takes a very long time to import or save, 8 seconds to render; no idea why.
P.p.s.: The pages didn't import on dev.twn, with Fatal error: Call to a member function getPrefixedText() on a non-object in /www/dev.translatewiki.net/w/extensions/LiquidThreads/classes/Hooks.php on line 671

After Reedy's https://gerrit.wikimedia.org/r/105839 with Nikerabbit's assistance, no more fatals are seen and I managed to mark, re-revert and re-mark, perfectly reproducing what done on Commons (ahem, I had forgotten I wasn't translation admin, Kaldari fixed).

What's left to do in Translate if anything?

Nothing... And this isn't really a Translate bug either now
