Text output before AskUserQuestion gets last line cropped by question widget

Description

When a skill (or any tool-using flow) outputs text immediately before calling AskUserQuestion, the last line of the text output gets visually cropped/hidden behind the question widget that renders below it.

Steps to reproduce

1. Use any skill that outputs text then calls AskUserQuestion (e.g., IDKWTD /session, gstack skills)
2. The assistant outputs a paragraph of text, then calls AskUserQuestion
3. The last line of the text paragraph is partially or fully hidden behind the question component

Expected behavior

All text output should remain visible above the question widget.

Actual behavior

The last line of text before AskUserQuestion is cropped. For example:

"You've got paths but can't pick one because every direction has tradeoffs and none of"

The rest of the sentence ("them feel clearly right. I get it.") is hidden behind the question UI.

Screenshot

The cropped text is visible in the terminal — the line gets cut off right where the AskUserQuestion widget begins rendering.

Environment

• Platform: macOS (Darwin 25.3.0)
• Claude Code CLI
• Reproducible across multiple skills (IDKWTD, gstack)

Notes

This is not specific to any one skill — it affects any flow where text is output immediately before AskUserQuestion. Related but different from #39867 (which is about option description text within the widget being cut off).
