Totally understand that, but without equal brackets, it doesn't comply with the standard (been in IT for 25 years). Something is getting automagically fixed somewhere, that or automagically broken. I think it's the first, but I don't (won't) use other browsers, so I don't know how they are behaving (or not).
I'm using Firefox, so it's not an uncommon browser, maybe it's a bug.
Seriously, just try hovering over your links, they show unequal brackets. Either both brackets need to be there, or neither.
Not trying to be a pain in the rear, but someone else IS going to have the same problem and not know why. So, I'm trying to help get future links posted, properly. I don't care, I know how to cut and paste to fix it, others might not.
