WithConstrainedTabbing 
Edit
withConstrainedTabbing is a React higher-order component adding the ability to constrain keyboard navigation with the Tab key within a component. For accessibility reasons, some UI components need to constrain Tab navigation, for example modal dialogs or similar UI. Use of this component is recommended only in cases where a way to navigate away from the wrapped component is implemented by other means, usually by pressing the Escape key or using a specific UI control, e.g. a “Close” button.
Usage
Wrap your original component with withConstrainedTabbing.
import { withConstrainedTabbing, TextControl, Button } from '@wordpress/components';
import { withState } from '@wordpress/compose';
const ConstrainedTabbing = withConstrainedTabbing( ( { children } ) => children );
const MyComponentWithConstrainedTabbing = withState( {
isConstrainedTabbing: false,
} )( ( { isConstrainedTabbing, setState } ) => {
let form = (
<form>
<TextControl label="Input 1" onChange={ () => {} } />
<TextControl label="Input 2" onChange={ () => {} } />
</form>
);
if ( isConstrainedTabbing ) {
form = <ConstrainedTabbing>{ form }</ConstrainedTabbing>;
}
const toggleConstrain = () => {
setState( ( state ) => ( { isConstrainedTabbing: ! state.isConstrainedTabbing } ) );
};
return (
<div>
{ form }
<Button isSecondary onClick={ toggleConstrain }>
{ isConstrainedTabbing ? 'Disable' : 'Enable' } constrain tabbing
</Button>
</div>
);
} );
