Created attachment 253338 [details] Testcase Testcase doesn't transition the zoom.
A transition is actually run, the transitionstart and transitionend events fire as expected. However, the value is not interpolated, either visually or as queried through the CSS OM.
Chrome does not transition this property at all, there are no events produced and no visual transition. Firefox does not support zoom, a non-standard property, at all.
