Reproducible: Always Steps to Reproduce: 1.Make sure there's a long enough list of extensions, working or not. 2.Click an extension near the bottom, making sure that the window needs to to scroll to it. 3.The window should scroll down partway, but not to the proper location, and instead, end up near the top of the item above the selected one. Actual Results: The extensions window did not scroll directly to the right extension entry, it instead scrolled to the top of the one above it. Expected Results: It should have scrolled directly to the selected entry. this happened in the newest non-cairo trunk build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060411 Firefox/3.0a1
