(from the bmo bug) Upstreaming from https://bugzilla.wikimedia.org/show_bug.cgi?id=55373 We're using bmo4.2's InlineHistory in bugzilla.wikimedia.org (with small CSS adjustments). Below https://bugzilla.wikimedia.org/show_bug.cgi?id=45051 comment 6, InlineHistory claims that MZMcBride marked bug 43689 as a duplicate of 45051. This is not true; Krinkle did that in comment 5, and MZMcBride only quoted the automatic comment. History of 43689 also shows that the duplication was not reverted and applied again (to rule out one potential reason). The only explanation I see is that InlineHistory "marked as a duplicate" detection is too eager. It should only trigger when that comment is at the end of the comment, in a separate paragraph. Could only find b ug 759768 which seems to be slightly related.
This change is now live. If there are any issues, do not reopen this bug. Instead, you should create a new bug and reference this bug. -- simon
