I was trying to debug something with
http://www.washingtonpost.com/ and so I had the page info window open. That site has an image on it which swaps out ever five seconds or so.
In page info, I collapsed the images section. However, when the new image loaded that section automatically expanded. IMHO, this is a bug.
Additionally when I gave up on it staying collapsed and simply scrolled past it, when the image loaded the list would automatically scroll to the top. IMHO, this is another bug.
