When editing tag wiki for thread-dump, I have noticed that there is already some text pre-filled in the edit window for that wiki. See Wiki for thread-dump tag - edit window.
But, this tag does not have any wiki yet and I do not remember filling in this text.
Q: Could it be a rejected wiki edit from some other user?
Q: Can you see it too? It this a bug or a feature?
I will edit the tag wiki anyway but I was just wondering where did this text come from.
