Subject: [PATCH] [WPE] Show application/vnd.hbbtv.xhtml+xml as XHTML
Reviewed by NOBODY (OOPS!).
The HbbTV edition of a broadcaster page is served as
application/vnd.hbbtv.xhtml+xml. WPE cannot show it: the type is not
among the supported non-image MIME types, so the response is downloaded
and the view reports a frame load interruption. Add the type to the
supported non-image MIME types and create an XHTML document for it, as
for application/xhtml+xml, so the page loads and parses as XHTML.
