Relative path using incorrect base url (html-fragment)

[juniorvanin-zz]

The strategy html-fragment is fetching script tags using base url from "host" page instead of the "target" page.

Example:

// host page: http://example.com/

<plastic-bag src="http://target.com/page.html" type="html-fragment" />
// page.html content:
<script src="/bundle.js" />

In this scenario, it's fetching http://example.com/bundle.js instead of http://target.com/bundle.js.
