I have an <input type="text"> box on a page I'm building that chrome is insisting on autocompleting with my email address, even though this box has absolutely nothing to do with my email address. I've tried many different `autocomplete=` settings, etc. Nothing stops Chrome. Help?

Update: pretty sure my problem is NOT autocomplete, but autofill. Chrome is filling this box even before I've focused to it, much less started to type anything.
