Reviewed by Eric Carlson.

As a prelude: at some point, WebKit fixed a bug where the `object-fit` CSS property was not honored
if set before media began loading in a HTMLVideoElement. Hulu.com sets it's video element's
`object-fit:` style to `fill`. When Hulu.com navigates to the next episode in a playlist, it resets
the <video>'s `width:` and `height:` style to 100%, causing the video to stretch visibly. Previous
to the mentioned fix, this bug would "hide" this behavior, by causing the renderer to ignore `fill`
and default to `contain`.

Add a quirk for Hulu.com that reverts to the previous (broken) behavior.
