What's the URL of the page containing the problem?
http://reviews.review-board.org/r/740/diff/#index_header
What steps will reproduce the problem?
1. Go to any diff page
2. Click a line to bring up the comments box
3. Observe that there is no caret in the edit box.
4. You can type text into the box, and backspace works, but no other
navigation keys work (arrows, home, end, etc.).
Clicking inside the edit box shows the caret, and then all keys work properly.
