When reporting this question on SF as an exact duplicate of this one over on DBA, the description of question 2868 on SF is pulled through, not the description of question 2868 on dba.se.
The comment that gets added was (before I applied an edit):
possible duplicate of [What is the best open-source email solution package](https://serverfault.com/questions/2868/what-is-the-best-open-source-email-solution-package)
possible duplicate of [I am using a MEMORY engine but MYSQL still writes to my disk…why?](https://dba.stackexchange.com/questions/2868/i-am-using-a-memory-engine-but-mysql-still-writes-to-my-disk-why)
which I expected.
Is this behavior-as-intended (i.e. the feature is intended for marking duplicates within one site, and cross-posted duplicates should be reported some other way) or a bug?
As a side question: would it be worth implementing a distinction between questions from different users that carry the same meaning (which just want to be closed with a link to the older question) and cross-posts (in which case merging the answers, before closing the copies on all but the most relevant site, makes more sense)?
