The comment box on differential pages is at the very bottom
On large diff pages the comment box must be scrolled to. This is really annoying because the diff loads as you scroll.
This is also inconsistent with the rest of the panels on the diff page (There is nothing else below the diff)
To reproduce this, load a particularly large diff (>1k sloc) and try to scroll to the bottom of the page.
The loading of diff chunks causes scrolling stuttering.
