Menu created with menu application and positioned "after header" shows up when the page is printed

How to reproduce:

• install the menu application
• create a menu and display this menu "After Header"
• go to a page (e.g. Sandbox)
• print this page using the print function of the browser (ctrl + P)
  • a non-accurate preview of what will be printed can be seen using the menu "More actions -> Print preview"

Actual result:

• The menu will be printed along with the page
• The CSS of the menu will, however, not be applied, so the menu will take a lot of room from the printed page and will be ugly. Actually, the way this menu is printed depends on the browser (somehow)

Expected result:

• Since other navigation elements of the page are not printed, I would not expect this menu to be printed
• I would at least expect it to look like the print preview, and be styled properly
• The most bothering thing is that the menu is actually taking a big space in the page, without providing information that is more interesting than other elements of the page
