Describe your issue

I'm currently using Storybook to document components and during the customized Headless Input component accessbility testing, a warning about the attribute aria-invalid being empty was triggered:

The empty aria-invalid can also be seen on element inspection in the reproduction URL.

It happens due to how Headless Input currently renders the aria-invalid:

'aria-invalid': invalid ? '' : undefined,

I believe that rendering this attribute with a true value ('aria-invalid': invalid ? 'true' : undefined) solves this issue, and this is probably cause by how React misshandles aria-* attributes that require a valid value (in JSX this is considered booleanish, meaning that accepts boolean, 'true' or 'false', but in HTML just ="true" or ="false" is expected)

References:

• ARIA state or property has valid value
• Required attribute requirements

Note:

Apparently, MDN says that any value different than 'true', 'false', 'spelling' or 'grammar' will be treated like 'true', but as we can read in the references, this attribute must have a valid value (any of the previous ones).
