refs 7eda410dc3
- ensures any `<DOCTYPE html>` (or equivalent) served when fetching preview html is passed through when replacing iframe contents
- replicates across all previews the fix for missing attributes on the `<html>` element that was put in for the design settings preview - using `documentElement.outerHTML` in place of `documentElement.innerHTML`
