Describe the bug

When setting the clientId in the PubSub client to a fixed value to enforce security best practices (such as creating a least privilege policy to limit the connection with a specific clientId only), the application enters an infinite connection loop, as the client tries to connect with the same ID causing a DUPLICATE_CLIENT_ID disconnection error.

Expected behavior

The client connects

Reproduction steps

Create a React app, add Amplify PubSub as per documentation
Additionally set the clientId to a fixed value
