I think the new feedback feature is broken. I've enabled it and set it to display on the righthand side of the screen, yet it remains perpetually "on" and display from the bottom.
Unfortunately, I haven't been able to reproduce what you are seeing.
Are you seeing the feedback at the bottom of the page like this everytime? What happens if you press the cancel button? What browser are you using and what version is it on?
