In my watchlist I see:
(topic | history) . . Wikipedia talk:Flow/Developer test page; 05:40 . . <em>Username suppressed</em> suppressed a comment (testing suppression).
I'm not an oversighter, so I should be able to see that in the first place.
More importantly, suppression log entries should not be hitting the recentchanges table at all.
Unsure if/how bug 57855 is related.
Version: unspecified
Severity: major
