Description: aframe master 0.7.0 (Date 2018-02-10, Commit #5f4179d) stats vr-mode-ui and inspector not shown ( behind sky)

• A-Frame Version: aframe master 0.7.0 (Date 2018-02-10, Commit #5f4179d)
• Platform / Device: fedora chrome
• Reproducible Code Snippet or URL:https://a-frobot.github.io/aframe/examples/boilerplate/hello-world/

if i remove the sky and the set the background none i can see the stats but the vr-mode-ui is not clickable -> https://subsequent-morocco.glitch.me/ looks like a z-index problem and all the gui elements are behind the sky

removing this css style solved my problem https://github.com/aframevr/aframe/blob/master/src/style/aframe.css#L58

but do not know if this is needed for other fullscreen browsers?
