The VisualEditor toolbar has a section for "notices" between the "Leave feedback" and "Cancel" buttons. This includes the "You are using an alpha version of the VisualEditor. It may be slow and make erroneous changes - please check each edit that you make." notice, as well as a relevant edit notice where one exists, separated by a gray line. However, when there is no edit notice, the section still says "2 notices" and places an empty div resulting in a gray line at the bottom.
