So, I reported a bug to tech support, but they said they've never encountered it before and they can't replicate it, so they asked me to test it on a different browser. So I decided to crowdsource it.
Basically what happens is that even after I scroll down on the page a lot whatever article is last on the sidebar still remains clickable. I usually scroll by clicking the mouse wheel down, but that same action opens a new tab in chrome, so this becomes annoying when it results in random tabs opening. So, anyone encountered this bug before? ETA: Forgot to say, this happens intermittently, not sure how or why.
If that explanation doesn't make any sense her's a helpful screenshot:
