This question already has an answer here:
I proposed an edit for this question, where I changed the mark up to make the given url an actual link (when I viewed the answer, I couldn't click the url, because it was not rendered as a link).
My edit got rejected, which is fine, when this edit is too minor (two reviewers marked it as too minor), but another one rejected it with the comment
No actual change, the original has a link.
When you take a look here, where my edit was rewieved, you can see that the change is only in the markup and the rendered output is the same. So here the url is already rendered as a link, although it's not a link in the mark up.
Why is rendering of this url different in this view from the actual display of the answer? Is it a bug that it is different?
