## The current behavior

The full value of the `key` is very difficult / impossible to find and use in the interface of the React Devtools.

![Kapture 2020-04-22 at 11 47 47](https://user-images.githubusercontent.com/1935696/79997715-25222680-84ba-11ea-97ba-51f1679a8c91.gif)

Only managed to find it by accident :(

## The expected behavior

The `key` is visible in the props list to the right.

### Detailed Proposal

As mentioned below in https://github.com/facebook/react/issues/18702#issuecomment-617924196

Add a light divider and new section in the props panel to the right.

Potentially also add a question mark that shows an explanation about the fact that things in this section are not really props.

        Suspended state cannot be toggled while Suspense components are hidden.
        Disable the filter and try agan.
      </div>
    );
  } else {
    return (
      <div className={styles.CannotSuspendWarningMessage}>
        The selected element is not within a Suspense container. Suspending it
        would cause an error.
      </div>
    );
