I think the pending edit and closed as "Possible Duplicate" should not exist in the same question. The reason is following case:
- Someone start a "Possible Duplicates" close voting in a question. According to the Stack Overflow's rule, this is equal to suggest edit the question; we can call it "Pending Version A."
- Another one edits the question, and a new pending version will be appeared. We can call it "Pending Version B."
- Then the close voting and "Pending Version A" are approved, and the question
will be added a description, like this:
Who is the Community user?
- The last, "Pending Version B" is approved, and "Version A" is replaced by "Version B"; the "Possible Duplicates" info disappear, and the closing as "Possible Duplicates" is invalid.
