 // TODO(tiger): Right now there is no support for rewriting URLs inside CSS
 // documents which leads to bugs like <https://crbug.com/251898>. Not being
 // able to rewrite URLs inside CSS documents means that resources imported from
 // url(...) statements in CSS might not work when rewriting links for the
 // "Webpage, Complete" method of saving a page. It will take some work but it
 // needs to be done if we want to continue to support non-MHTML saved pages.
