One of the worst bugs with twitter webpage is this. When scrolling down to check overnight tweets on the timeline, and when you have scrolled hundreds of them and you click a regular tweet or a quoted tweet to check responses etc (thankfully quoted tweet opens as a popup lately; it used to open a different page earlier causing pissed_level++) and dismiss the popup, the feed is scrolled back up to the top, and to add to the misery, the tweets in the waiting will be expanded too. You would have to be a regular user of twitter in order to make sense of this and/or empathize.
