In current implementation, if multiple iframe elements point to the same URL, we only create one file and make all the
elements point to that file. However, iframe content is usually modified by script, which means iframe pages with
the same URL usually have different content. To ensure the content is correctly captured, we now create one file for
each iframe main resource. This also matches behavior of other browsers.

Test: WebArchive.SaveResourcesIframesWithSameURL
