The `<TabPanel />` component implements the a11y requirements for a
[tabpanel](https://w3c.github.io/aria/#tabpanel) based upon the context within a `<TabsProvider />`
component. The component automatically sets the `id` and the `aria-controlledby` properties from the
`TabsProvider` context. It is not recommended to use this component outside of a TabsProvider.

The `<TabPanel />` component **does not** filter the correct tab to display itself. This must be
implemented by the developer.

### Example Implementation

```tsx
// Example
const [selectedTab, setSelectedTab] = useState('tab-1');

const TABS = { 'tab-1': 'One', 'tab-2': 'Two', 'tab-3': 'Three' };

return (
  <TabsProvider selectedTab={selectedTab}>
    <TabList onTabSelection={setSelectedTab}>
      <Tab key="tab-1">Tab 1</Tab>
      <Tab key="tab-2">Tab 2</Tab>
      <Tab key="tab-3">Tab 3</Tab>
    </TabList>

    {/* There should only be one. A single TabPanel component should wrap all content that is controllable by the TabList */}
    <TabPanel>{TABS[selectedTab]}</TabPanel>
  </TabsProvider>
);
```

## Stylization

This element supports the usage of `className` and `style` props to allow for custom dynamic theming
and element identification.
