Today I found the diff in URL by Kghbln, who is in "editor" group, which has "autopatrol" permission, not patrolled. Expected: the edit is autopatrolled.
His edits seem to be normally autopatrolled everywhere, except in user talk namespace. Checking <https://www.mediawiki.org/w/index.php?title=Special%3AContributions&contribs=user&target=Kghbln&namespace=3>
I found out that the last edit which was correctly autopatrolled is <https://www.mediawiki.org/w/index.php?title=User_talk:Satyamcompany&oldid=680195&diff=prev> as opposed to <https://www.mediawiki.org/w/index.php?title=User_talk:Shirayuki&diff=prev&oldid=684848>.
Something happened between April 28 and May 3: it was a busy period for Echo ([[wikitech:Server_admin_log/Archive_22#April_30]]) and saw several changes to Echo deployed as part of [[mw:MediaWiki_1.22/wmf3#Echo]] and more, while the only core change mentioning patrol or talk is gerrit change 59086 (related to Echo anyway), so filing here.
