THE SAME ISSUE AS LAST WEEK: Chat window no longer produces any output. No process flow or response is visible.

Describe the bug

When using the Flowise chat interface, new responses from the agent or flow nodes do not automatically appear in the chat window after submitting a message. The chat window remains blank until I manually resize the chat pane, close and reopen the window, or refresh the page. After performing any of these actions, the missing response appears as expected.
Additionally, I do not see any “gear” icons (settings indicators) in the Agentflow while the flow is running, which normally should appear to show active node processing.

To Reproduce

Start a chat with a flow (any flow, including simple LLM or multi-agent flows).

Enter a prompt and submit.

Observe that the chat window remains blank (no new response).

Resize the chat window, close and reopen it, or refresh the page.

The previously missing response now appears.

Expected behavior

The chat window should automatically update and display new responses as soon as they are generated, without requiring manual resizing, refreshing, or toggling the window.

We're testing a pub/sub streaming related issues and have a PR for the fix, as this problem only happens at scale, we wanted to wait for this issue to happens again, then deploy the fix to see if it does fixes that. Sorry for the inconvenience! We're working hard to identify the root cause as its not easy to reproduce.
