Firefox + white.css: Backgroundcolor switches to Black in Fullscreen

[emasch]

Hi,
I use Version 3.3.0 (from bower.json) fo reveal.js. I've also seen those Tickets: #668, #1408 and #1516, but they doesn't fix the problem for white.css for Firefox on Mac OS.

If I toggle fullscreen via 'f', the background-color switches from white to black. I have to add the following css to change the color back:

    html:-webkit-full-screen-ancestor {
        background-color: #fff;
    }

    html:-moz-full-screen-ancestor {
        background-color: #fff;
    }

In the reveal.css the color is inherit, which means it usees the browser default, which is black in firefox 47.0 on Mac OS 10.11.
