What are "Experimental Features" in Safari?
Safari settings on iOS 11 have an Advanced screen full of "Experimental Features." I searched, but did not find any explanation of what each one of them does. For many, it is not even clear to me if turning one of them ON enables, or disables, that particular feature.
Is there a guide, or KB article, somewhere explaining them?
