That field in question used by Gijo does NOT have the same label / information as the other one you reference. It is a one-click radio button and something a standard user might try out considering “Deferring Javascript” is what the feature is called. Yes, it’s there on the other radio button, but the logic behind radio buttons is that they are seperate choicecs – so the information, logically, would only apply to the first selection. Besides, why is this called “Defer Javascript” when it is more like “Hide JavaScript from page speed tests and load them asyncronously for users”? I would definitely not expect it to do that. If this is meant for testing scripts agains page speed tools then why isn’t it clearly labeled as such?
At best this is bad UI that should be fixed.
I have to agree this could have been handled more clearly initially to avoid this confusion – but you’re not making it any better by still not understanding (or pretending not to understand) the issue.
