Before I respond, I am finally back on this site after a year just about! I plan to be on here for now on! I'm sorry for the break.
Based off my experience, I think this is just simply a HTML formatting issue. But I'm not sure, as I am not a web designer, just an artist and programmer. Messing up HTML pages can happen often, especially if it has messy spagetti code. This is why whenever I code, I like to keep everything as tidy as possible. But please DONT take my word for it, I am NOT smart enough to know these things just by guessing.
Edit 8:54 - I also do not think this change was intentional, but hey, thats just me
