Websocket Connection Closed: When `BrowserCriClient` destroys an extra target while that target is being initialized, the App crashes

[cacieprins]

Current behavior

If BrowserCriClient's _onTargetDestroyed event handler is triggered while the _onAttachToTarget event handler is pending the Fetch.enable CRI command, the app can crash with an uncaught exception, Error: WebSocket connection closed.

This is a separate manifestation of the WebSocket connection closed issue that was resolved in the CriClient class in v13.13.1.

Desired behavior

Hello, any update on this? We're consistently experience this failure on our automated test in CI. Would like to know when the fix can be possibly released? Thanks!

@allenbilar There's a PR open that will hopefully fix this. We won't really know until it's released and used by users to ensure this covers all of these issues. https://github.com/cypress-io/cypress/pull/30174
