I think that it is to do with the way that this site interprets them. The semicolons seem to "throw" this site. And not just this site - have a look at how Google lists MSKB links - not as the original (or at least they didn't used to be).
It isn't a big deal and once you know the workaround it just involves a few extra clicks.
Every time you or somebody else posts a link to microsoft KB that interests me I save it in a special folder that I have created in my Favourites Folder I have also made a backup of this folder. I hope your head is now clear after that inebriated holiday you had. LOL
