Fullscreen TUI: assistant text dropped in turn continuations after AskUserQuestion answers

Summary

With "tui": "fullscreen", assistant text emitted in a turn continuation after the user answers an AskUserQuestion is not rendered — the transcript view jumps from the "User answered Claude's questions" block straight to the next tool-call summary and question box. The prose between them (which can be the entire explanation a question depends on) is silently invisible to the user.

Environment

• Claude Code 2.1.226
• macOS (Darwin 25.5.0), ghostty terminal
• "tui": "fullscreen" in ~/.claude/settings.json
• Model: claude-fable-5

Repro

1. Set "tui": "fullscreen".
2. Have the assistant ask something with AskUserQuestion; answer it.
3. In the same turn continuation, the assistant emits: (a) a text block, (b) one or more tool calls (e.g. Write), (c) another text block, (d) another AskUserQuestion.
4. Observed: neither text block renders. The screen shows the answered-question block, the tool-call summaries ("Wrote 2 memories"), then the next question UI.
5. Expected: the text blocks render like assistant text in any other turn.

Notes

• Assistant text in turns triggered by other events (e.g. incoming teammate messages in an agent-teams session) renders normally in the same session — the drop is specific to post-AskUserQuestion-answer continuations.
• Hit repeatedly in one session (multi-question workflow): the user experienced it as "questions keep appearing with no context," since every explanation written between an answer and the next question vanished.
• Session had CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 set, in case relevant.
• No supacode/OSC hooks active at the time (SUPACODE_SURFACE_ID unset; the only PreToolUse hooks matching AskUserQuestion no-op without it).
