Partial refresh'ing with a response that contains an <iframe> changes title

[tedtate]

Steps to reproduce

1. Trigger a partial refresh on a page where the XHR response contains an iframe (This is easy to repro within Shopify if you would like a link).

Results

The title of the page is updated to Edit Comment.
This also might cause some other side-effects which I'm not aware of.

Why does this happen?

Turbograft contains a regex which tries to determine whether a response is a new html document or not and this trips it up:

turbograft/lib/assets/javascripts/turbograft/document.coffee

Line 3 in 1dbd24e

if /<(html|body)/i.test(html)

.

@TheMallen have you get a chance to look at this yet?
