[BUG] AskUserQuestion is blocking text #23862

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

In the CLI, every time Claude outputs a bunch of text and then immediately calls the AskUserQuestion tool, AskUserQuestion ends up covering part of the original output. You can only see the text afterward if you cancel it.

What Should Happen?

AskUserQuestion will not cause obstruction

Steps to Reproduce

You can easily reproduce this issue. First, have Claude Code output a long passage of text, then have Claude Code call the AskUserQuestion tool. Finally, have it do both together in one go.
