This test fails as it is. Why should the headers/footers been hidden here?

Also I dont think this is the right test to check for the visibility of the
headers and footers. This test checks whether the settings reflect the
capabilities of the currently selected printer, but headers and footers do not
depend on the printer, right? If so, I believe a new test, specific to headers
and footers.

Restored change - will create a separate CL for JS tests.
