We had some code in the ReviewRequestPageView to expand any entries that contain an element with the window's hash, but this was only looking at children of the entry views. For review entries, the entry view's element itself has the ID, so we weren't doing anything. The page would scroll purely based on the browser's behavior. This change makes it so we test both the entry's element as well as look for any children of that element. I've also put the actual scroll call into a requestAnimationFrame() callback to allow the page to reflow if necessary when expanding the entry, which helps do a better job if the entry being expanded is at the bottom of the page. Testing Done: - Ran js-tests. - Opened pages with #reviewXXXX hashes in the URL and saw that the correct review was now expanded and scrolled to.
