Log shows patrol entry for the third edit and the revert,

All three of the edits no longer have a "Mark as patrol" link.

I don't remember if we used to add patrol entries for all three. We totally should, though. It's almost untraceable otherwise.

action=rollback sets rc_patrolled = 1 for all the edits which gets reverted and does not add a patrol log for these edits. Looks like working as designed (maybe needs documentation on mw.org). Maybe needs a redesign here.
