Question

An AI agent built this modal dialog component. It opens and closes correctly with the mouse and looks right. A keyboard-only and a screen-reader user file complaints in the same week. Find the accessibility defects.

jsx
function Modal({ open, onClose, title, children }) {  if (!open) return null;  return (    <div className="overlay" onClick={onClose}>      <div className="modal" onClick={(e) => e.stopPropagation()}>        <h2>{title}</h2>        {children}        <button onClick={onClose}>Close</button>      </div>    </div>  );}
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
