Comment on attachment 50108 [details] patch Please preserve the old Chromium WebKit APIs temporarily to avoid requiring a 2-sided patch landing? Add a comment to the old method with the text "DEPRECATED", then after the Chromium side switches over to the new API, do another WebKit patch to remove the deprecated method.
