Summary

TUI streamed text still replaced on finalize - variant without tool calls (related to #15452)

#15452 was fixed by #15573, but a related variant still occurs. When the user sends a multi-part message (comment + question), the assistant streams a response addressing the first part, then the entire response disappears and is replaced with a shorter response addressing only the second part.

This variant does NOT require tool calls mid-response - it happens on pure text responses.

Environment: macOS Sequoia, Node v25.6.0, OpenClaw 2026.2.13 (commit 5cd9e21, #15573 merged), anthropic/claude-opus-4-6, TUI, webchat channel

Steps to reproduce

1. Open openclaw tui
2. Send a message containing both a comment/context AND a question (e.g. "I had this experience with a recruiter calling me three times... Also, can you research this company?")
3. Watch the streamed text - assistant begins responding to the first part (the comment)
4. Mid-stream, the entire response disappears and is replaced with a shorter response addressing only the second part (the question)
5. The first part of the response is completely lost - not truncated, fully replaced

Expected behavior

Full response (addressing both parts) is preserved after finalization.

Actual behavior

Response to first part vanishes after streaming for several seconds, only response to second part remains.
