Luckily, hosseinimr93 figured out where the problem is and that won't be necessary any longer. All we have to do now is pay attention to the number of empty spaces before the link in case of an edit. It's possible not to notice two empty spaces preceding a link, but it becomes improbable you won't see 3, 4, or more. So if a link suddenly turn unclickable, it's an easy fix.
