Re: [svgwg] Clarify <iframe> behavior in <svg:use> (#876)

Wrote some tests: https://psychpsyo.com/web/testing/svg/useElementShadowRootClosed.html
Results:
The shadow root is closed in all browsers. (WebKit, Chromium, Firefox)
Iframes visually show up in Firefox.
All sorts of scripts currently run inside the USE element in Firefox.
(the tests are written to verify that scripts don't run, but that's just me picking one option to see what Firefox currently does)
