Position relative for :host

[raphaelbastide]

I am not sure if this is the right place to post this suggestion, but I would suggest adding a position:relative; to the default CSS rules:horst. In this case, any element with absolute position children of :host would not overflow, except if the author wants it.

:host without position:relative;

:host with position:relative;

That's a great note -- change made in my demo client, and I'll add this to the spec.
