AskUserQuestion dialog auto-submits on mouse click without confirmation

Description

When an AskUserQuestion dialog is shown, a single mouse click on one of the options immediately submits that option as the answer, without requiring the user to press Enter or click a separate confirm button.

The user did not intend to confirm — they only clicked into/onto the option (e.g. to focus or read it) and the answer was sent automatically.

Steps to reproduce

1. Run Claude Code in a JetBrains integrated terminal.
2. Have the assistant invoke AskUserQuestion with a Yes/No (or any) set of options.
3. Click on one of the options with the mouse (do NOT press Enter).

Expected behavior

Clicking an option should focus/select it. Submission should require an explicit confirmation (Enter, or a separate Submit button/click).

Actual behavior

A single mouse click on an option immediately submits it as the final answer.

Environment

• Claude Code version: 2.1.193
• OS: Linux 6.8.0-124-generic (Ubuntu)
• Terminal: JetBrains integrated terminal

Notes

Reproduced live in a session: the assistant asked a Yes/No test question, the user clicked once with the mouse (no Enter press), and "Yes" was submitted immediately.
