screenfull.enabled = true in Android 4.3, but not supported

[chaenu]

First of all, thank you for your work!

I've noticed that screenfull.enabled returns true on the Samsung Galaxy S4 / Android 4.3 Stock Browser, where the fullscreenAPI isn't supported. But this is not a bug in screenfull, as document.webkitFullscreenEnabled returns true and the stock browser is pretending to support the fullscreenAPI (see https://code.google.com/p/chromium/issues/detail?id=180734).
The HTC One / Android 4.4.2 Stock Browser returns undefined as expected and therefore screenfull.enabled is false.

Do you see any possibility to deal with this false behaviour?

Not really. Only way I can think of is browser-sniffing and not super interested in adding that.

Yes, I fully understand this. Thanks for your fast response.
