autofocus is currently limited to these current elements: https://webkit-search.igalia.com/webkit/rev/549cfddb2c8f134d24510de87c8bbb41c20e055c/Source/WebCore/html/HTMLFormControlElement.cpp#229-238 However, autofocus is a global attribute, so editable elements or tabindex > -1 elements should be autofocusable as well.
