<!-- end auto-generated rule header -->

Enforce that `aria-hidden="true"` is not set on focusable elements.

`aria-hidden="true"` can be used to hide purely decorative content from screen reader users. An element with `aria-hidden="true"` that can also be reached by keyboard can lead to confusion or unexpected behavior for screen reader users. Avoid using `aria-hidden="true"` on focusable elements.

## Rule details

### Succeed
```jsx
  <div aria-hidden="true" />
  <img aria-hidden="true" />
  <a aria-hidden="false" href="#" />
  <button aria-hidden="true" tabIndex="-1" /> // `tabIndex=-1` removes the element from sequential focus navigation so we don't flag it.
  <a href="/" />
  <div aria-hidden="true"><a href="#"></a></div> // This is also bad but will not be handled by this rule.
```

### Fail
```jsx
  <div aria-hidden="true" tabIndex="0" />
  <input aria-hidden="true" />
  <a href="/" aria-hidden="true" />
  <button aria-hidden="true" />
  <textarea aria-hidden="true" />
```
