Comment:

 [attachment:"49288.diff"] adjusts the CSS rules and alters the postbox.js
 to be able to read all metabox holders to add the empty class.

 Instead of the default 250px height (as seen on Dashboard) the Edit empty
 holders will have a 50px height to avoid a big blank space at the bottom
 of the page (i.e. for advanced-sortables). It also enables the `Drag boxes
 here` message for resolutions above 1800px.
