Yes, did you notice those in the middle, right ?
They were placed there buy the editor automaticaly, just after I clicked preveiw post.
Weird ? Yes, but I found why. The link I'm using as an example I placed on Microsoft Word File because I use to keep a file on WORD of all mods I like and use just to make my life easier to organize and for upgrades, check diferences. Same as I did with yours, visually nothing chances but I think WORD uses weird HTML or something the scroll this up. I did that as I was using exactly the same link for several tests it's faster than going to Google and check for the same link all the time, you know.
But now I just copy/paste directly from Google and this was what I've got:
HTML Code:

You'll see those between the link were gone but a lot of tags still remains the same and conparing the raw link with the this one those tags are causing this errors.
Sorry bugging you around with all those long posts I'm just trying to be usefull.
