Break-before and Break-after do NOT accept "region" in IE11+ (but accept "always")

[FremyCompany]

It would work on IE9/10 but fails on IE11 because they added support for "break-before" and "break-after" but not the "region" value. As I'm relying on "currentStyle" in IE to compute the cascaded value of the property, and as the declaration is dropped by the browser (unlike in IE10 where it's conserved as an unrecognized property), I get no break information back.

Workaround: Use the value "always" and it should work fine.
