I tried to retag [this question][1] to add the [tag:windows] and [tag:windows-xp] tags, but it wouldn't let me submit my edit because it said that it was less than 6 characters:

At first I thought that it was because of [this issue][3] because I accidentally did something in the body without noticing, so I clicked Cancel and then tried to edit again and it did the same thing. I tried again and again and always got the same problem. So I'm sure that I didn't touch the body, only the tags.

The strange thing is that I successfully submitted [another retag][4] today and several retags in the past without getting this problem, and I regularly see tag edits on Stack Overflow where I have the privilege to review suggested edits, so normally edits just editing the tags should be allowed.

Is there a reason why I couldn't submit this specific retag without editing the body while I've submitted many other retags in the past without any problem? If this is a bug, please fix it.
