+<!--
+ Tests that setting a fixed top margin in the compositor results
+ in the margin being applied to an element fixed to the top.
+
+ The fixed margin is specified as a test-pref in reftest.list.
+
+ The purpose of the fixed margin is to compensate for the transform that the
+ dynamic toolbar applies to the entire content area. We don't have a way of
+ simulating that transform in a reftest, so the fixed margin in isolation will
+ cause the fixed element to be offset from the top of the screen, and in
+ the ref page we use a regular CSS "margin-top" to match the rendering.
