[BUG] AskUserQuestion widget truncates last line of preceding assistant text #30422

Preflight Checklist

• I am using the latest version of Claude Code

What's Wrong?

When Claude outputs text followed by an AskUserQuestion tool call, the last line of the assistant's text response gets clipped/truncated by the question picker widget rendering on top of it. The text is cut off where the interactive options UI begins.

What Should Happen?

Expected Behavior

All assistant text should be fully visible above the question picker widget.

Actual Behavior

The last line of text before the question widget is truncated — the widget appears to overlap or clip it.

Error Messages/Logs

Steps to Reproduce

1. Have Claude output a multi-paragraph response that ends with text immediately followed by an AskUserQuestion tool call
2. Observe that the final line of the prose text before the question widget is partially or fully hidden
