too wide page in edit mode

too wide page in edit mode

With free flow scripting active in functions section but not only in that place (in scripting part of the forms forms and in html views the same happens ), when I use Chrome whenever I activate  Refer Fields section from the left and I change the function (in functions sections) or I save the script, the page becomes very wide and I the horizontal scroll is activated. The following short screencast contains an example  http://screencast.com/t/BeZbkfmc
