aude added a comment. git bisect finds https://gerrit.wikimedia.org/r/#/c/244407/ (Effectively remove EDIT_DEFER_UPDATES flag) is causing the issue.
We use SiteLinkConflictLookup (SiteLinkTable) to check for site link conflicts when saving an edit. For merging, it's two consecutive saves (save the old item, removing stuff then save the new item with everything). Before, we must have executed the SiteLinkTable update immediately on save and now it is deferred until later in the request (e.g. until after the second save). deferring is generally the right thing to do, but we need to figure out a way to work around this issue that doesn't cause problems with merging or other things.
