google chrome and wordpress: ckeditor freezes bug

I discovered a bug with ckeditor on wordpress 3.x and google chrome (the bug does NOT occur with ie8 but so far only with google chrome).

You can see it going to this website, with google chrome only:

1. Click on "Test Post" on the home page to see the full version of that post (with comments).
2. Click on the "reply" link to any existing comment, and try to leave a nested reply. Ckeditor freezes, unless you press the "source" button.
3. (The issue doesn't seem to occur if you just press "leave a comment" link, i.e. when you are not nesting the ckeditor textbox.)

update: I've turned off threaded/nested comments as a workaround, so the above directions no longer apply (to my website).
