Steps to reproduce:

@media values max-height, min-height, max-width, min-width are tested including page margin when printing.
These values should return available viewport size, therefore without print page margin. 
Other browsers like Chrome and IE don't include page margin here.
Including the page margin in this case makes the attributes unusable, because the page margin is set by users and cannot be read by css in any way, so the available viewport size cannot be found out.

For example @media only print and (min-height:1122px) { ... } is accepted for A4 page size in 96dpi regardless of the page margin. 
But if I have set standard 0.5in top and bottom print page margins, the (min-height:1026px) should be maximally accepted for such setting. It means (1122 - in*dpi) = 1122 - 1*96 = 1026. Like in Chrome and IE.
