[GTK][EFL][Qt] New tests fast/regions/region-rule-nested-region-rule.html, fast/regions/region-styling-mediaquery.html are failing
https://bugs.webkit.org/show_bug.cgi?id=106168

Reviewed by Csaba Osztrogonác.

Specify a margin-top: 0 both for the h1 element that is flowed into region and the h1 element in the ref test to ensure
the h1 element is displayed at the same position in the region and in the containing article element.
Also, cleaned up the tests a little.
