[Nan Wang]

The input types could be mapped more expressively for help ATs to differenciates these fields from other text fields.

Slightly better to use auto:

    auto* node = m_object->node();

> Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm:2521
> +        if (node && is<HTMLInputElement>(*node)) {

The is<> function handles null checks if you pass it a pointer:

    if (is<HTMLInputElement>(node)) {

> Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm:2522
> +            HTMLInputElement& input = downcast<HTMLInputElement>(*node);

Best style is to not repeat the type:

    auto& input = downcast<HTMLInputElement>(*node);

> Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm:2531
> +            const AtomicString& type = m_object->getAttribute(typeAttr);

Should write:

    auto& type = input.attributeWithoutSynchronization(typeAttr);

Instead of going back to the accessibility object, now that we know this is an input element.
