Comment box is now in footer after wp 285 upgrade

Comment box of comment form is now situated in footer since upgrade to wp285

I had a text widget in sidebar containing an iframe ad at top of right sidebar and that was also appearing both at top of right sidebar and in footer above the comment box —in the footer

I removed the text widget and the ad went away from footer and now just comment box of comment form is in the footer with rest of widgets behaving themselves in the sidebar.
