For the sake of completeness, I'd like to mention that this feature is also
used in the Hbbtv browser shipped with Samsung TVs, as Giuseppe Pascale from
Opera already pointed out in a recent discussion[1].

That, together with what it was mentioned about the SmartTV Alliance using
it, means that pretty much the whole TV world is relying quite a bit on this
thing nowadays, so it would be great if we could have it integrated and
supported upstream.

That being said, we at the Samsung would be happy to support this feature
actively in WebKit, both by helping with the patch that's already in
Bugzilla [2] *and* maintaining it in at least one port. Should that be the
case, the obvious choice for us would be the WebKitGTK port, since that's
what we currently have on our TVs.

Problem is that the patch in [2] is quite old already (Jan 2012), so it
would be awesome if Kyounga Ra attached a newer version of it, since that
one depends on some parts that are now deprecated or simply refactored in
some way, as I could check today while experimenting with it on top of
latest WebKit [3].

Last, regarding to tests, just to mention that Opera has recently submitted
tests for this feature (see [4]). This would be IMHO another good point to
keep in mind here, since we could import them in WebKit too.

What do you think?
