Setting cq- since there's some build breakage in here.

Could use a tighter covariant return type for these.

This check should be reversed so the virtual dispatch goes last.

> +            if (element.isFocusable() && element.inDocument())

Same here.

> Source/WebCore/html/HTMLImageElement.h:117
> +    virtual HTMLElement& asHTMLElement() OVERRIDE FINAL { return *this; }
> +    virtual const HTMLElement& asHTMLElement() const OVERRIDE FINAL { return *this; }

Could use a tighter covariant return type for these.

> +    virtual HTMLElement& asHTMLElement() OVERRIDE FINAL { return *this; }
> +    virtual const HTMLElement& asHTMLElement() const OVERRIDE FINAL { return *this; }

Could use a tighter covariant return type for these.

Missing & here since you're assignin to an Element*.

Ditto.

> -                    Element* nextElement = const_cast<HTMLElement*>(toHTMLElement(formElementList[nextElementId]));

Ditto.
