After updating Chrome to version 46, scrolling ceases to work in Differential, when viewing a revision after clicking on any inline comment.
Mouse wheel, keyboard arrows/pgup/pgdow/home/end, grabbing scrollbar - nothing works while there is a valid hash in the URL (e.g. #inline-3673). Viewport stays centered on the inline comment and there is no way to get out, except for manually removing the anchor from URL and reloading.
