What's Wrong?

When toggled into expanded view if the agent request permission for an action it will "fall through" and the agent runtime will hang until you kill the request and manually request the agent to retry.

What Should Happen?

When an agent requests permission it should stack on top of the text input view so toggling out of the expanded view surfaces the permission request. Or at the very least pending permission view needs to be accessible by the user.

Steps to Reproduce

1. Ask Claude a question that for a command that doesn't require permission followed by a command that does. Such as Check the current directory for hello.txt and if it does not exist create the file with the content "hello world".
2. When it executes the action it has permission for, use ctrl+o to enter the expanded view, until you see the permission prompt summary in the log.
3. The write permission dialog will not be present once you toggle off the expanded view.
