Subject: Fix jumping to anchors with offline style
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the style changes after the browser already jumped to an anchor,
the resulting browser position will be messed up.
So, after we changed the style we need to make sure that we jump
to the anchor again.
Since browsers do not jump to anchors that they already jumped to,
that means first jumping to the top, then to the actual anchor.
