Summary

Messages queued while the agent is busy (the "X pending" queue) are lost when the user refreshes the browser.

Environment

• OpenClaw version: 2026.2.1
• Channel: webchat

Steps to Reproduce

1. Open WebChat UI
2. Send a message that triggers a long-running operation
3. While agent is processing, type and send additional messages (they queue with "X pending" indicator)
4. Refresh the browser before the agent finishes

Expected Behavior

Queued messages should persist across refresh and be submitted when the agent run completes.

Actual Behavior

Queued messages are lost. User must retype them.

Root Cause

The message queue exists only in React state. No persistence layer.

Suggested Fix

Store the queue in localStorage keyed by session ID. On reconnect, restore the queue. Filter out stale entries (>24h) to prevent zombie messages.

We have a fix ready — will submit as PR.
