Summary:
Changelog: [Internal]
I think this started to break when https://github.com/facebook/react/pull/25441 was synced to RN. Before, `closestInstance` would only be non-null under Fabric, after it could be non-null in both. And we were using `closestInstance` to determine which data to send to `selectNode` in devtools. This diff makes a change to call `selectNode` once for non-fabric and once for fabric, one of them would not send anything to devtools frontend, this would make sure it works for both platforms.
