The (thanks) link still appears next to an edit that has been oversighted or otherwise suppressed. Clicking the link gives the confirmation as normal and clicking OK appears to send the thanks as normal (I'm waiting for confirmation of whether the thanks is received - I don't have access to oversight to test on one of my own edits). Suppression of an edit should also suppress the ability to thank someone for that edit. I spotted this bug at https://en.wikipedia.org/w/index.php?title=Wikipedia:Arbitration/Requests/Case/Manning_naming_dispute/Workshop&action=history where the edits from 00:26 to 02:37 on 13 September have been removed.
The user concerned has replied saying that they did receive the thanks: "You did thank me, and it seemed to appear normally. The view edit link gave me this, which goes to the oversighted diff. [...] there did not seem to be anything overly broken about it." The link given was https://en.wikipedia.org/w/index.php?title=Wikipedia:Arbitration/Requests/Case/Manning_naming_dispute/Workshop&oldid=572700018&diff=prev
