You're right. It seems to have been fixed. Mere weeks ago when you clicked on a line to see its annotation you literally could not see it behind all the ads, as in it was impossible to get to the annotation.
Just wanted to say you're not crazy - the ads have gotten bad even on the desktop. Ad blockers obviously solve the problem, but the UX is terrible if you're in the majority that doesn't use one.
I took this as an early sign of the website's eventual demise.
