Add a focus assertion for an invalid Password. The current tests invalidate only Role or Email. Password remains foobarbaz, which satisfies the eight-character minimum. A regression in the Password InputGroup/FormField ref or aria-invalid wiring could therefore pass both tests without focusing Password.
Add a case in cypress/component/Examples.spec.tsx that selects Developer, keeps the default Email, enters a password shorter than eight characters, submits, and asserts:
cy.findByRole('textbox', {name: 'Password'}).should('be.focused');🤖 Prompt for AI Agents

Remove the extra comma before the period.
The Guides/Accessibility/Form Validation page renders “receives focus, . A”. Remove the comma.
