You just follow the steps.  (Let's assume it's an <img>, which is
actually a paint source.)  If the element is out-of-document, CSS
can't affect it, and it displays as a paint source.  If the element is
in-document, but not being rendered, it displays as a paint source
(showing the image it represents).  If the element is being rendered,
then it displays like any other element.

Same.  <h1> is not defined as a paint source by HTML, so it only gets
used if it's being rendered.  If you set 'content' to make it a
replaced element and then set display:none, it falls under the generic
"not being rendered" condition and just displays as a solid
transparent-black image.
