- You can unify HTMLInputElement path and HTMLTextAreaElement path.
- dispatchFocusEvent and dispatchBlurEvent are public on Element

if (isHTMLTextFormControlElement(*m_private) {
    unwrap<Element>()->dispatchFocusEvent(...);
    dispatchKeyDownEvent();
    unwrap<HTMLTextFormControlElement>()->setValue(...);
    dispatchKeyUpEvent();
    unwrap<Element>()->dispatchBlurEvent(...);
} else if (isHTMLSelectElement(*m_private)) ...

Nice! I merged the calls but kept the if more restrictive to only fill inputs
and textarea fields like before. Thanks!
