!blogspot results in the relative URL /?q=bang+site:blogspot.com.
Redirecting to relative URLs breaks because it redirects to a URL like this moz-extension://xxxxxxx/?q=query+here+site:blogspot.com.
To fix this it makes all URLs absolute with the base URL https://duckduckgo.com/.
Already absolute URLs are left unchanged.
