In total there are now four functions to support this:
    virtual bool disallowFullscreenForNonMediaElements() const = 0;
    virtual bool fullscreenEnabled() const = 0;
    virtual void setDisallowFullscreenForNonMediaElements(bool) = 0;
    virtual void setFullscreenEnabled(bool) = 0;

Why two settings, and why are the first two getters needed at all? I feel like I
don't have the whole picture here...

See my other reply that explains why we need the two settings.

We need the two getters so that we can access them from FullscreenElementStack?

I applied your patch locally and tried removing this. It works because
FullscreenElementStack uses Settings, not WebSettings.

That's right, sorry. Removed now.
