[BUG] UI Corruption due to mutliple parallel agents requesting clarification

Preflight Checklist

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

What's Wrong?

When Claude code needs feed back from the user it presnts a list of options

1) Do this
2) Do that
3) Do something else

etc.

This worked fine until the most recent release, now if (particularly in plan mode) there are multiple parallel agents running and 2 or more of them need to ellicit a response from the user the ui becomes garbled because multiple lists get displayed on top of each other at times.

I've also observed that sub-agents ask for permission to read my project folder over and over which mnakes this worse (i.e. they seem to ignore permissions in the project .claude/settings.local.json)

What Should Happen?

I'm not really sure but I guess elicitation requests from subagents need to be queued and displayed to the user sequentially - not all at once
