botframework-webchat: Timed out while waiting for activity "2677ac02-c9ff-47a2-b140-d5af9cc7ad9e" which activity "fc025a2a-3f35-4241-b024-0d95285920eb" is replying to.

How to reproduce the issue?

1. Follow the setup from: https://github.com/microsoft/Agents/tree/main/samples/nodejs/copilotstudio-webclient
2. Fill Copilot credentials
3. Send any message and watch the Console

What do you expect?

There should be no timeout

What actually happened?

When connecting to Copilot, even though Copilot responded successfully, it only displayed the response after the timeout.

Additional context

No response

Reproduce the issue using the microsoft/Agents samples/nodejs/copilotstudio-webclient setup in Chrome with the Copilot credentials, then trace the console timeout involving the two activity IDs. Confirm why the response is displayed only after the timeout and verify that a normal Copilot reply appears without the timeout.
