instead.

Nice. Yes, I think the DIV elements will be much lighter weight, since we really
only need elements to supply us layout, font-rendering, and border painting.

Thanks for the suggestion. :)

I think this should be renamed. The name no longer matches what it is actually
doing.

[xjz, 2017/04/13 19:12:12]

Done. Renamed it to MediaRemotingExitButtonElement.

Done.
