What issue are you seeing?

#28235 introduced a bug in plan mode where codex does not wait for responses to questions. Based on the comments in that PR, it was only intended to affect default mode. There is also no way to disable this behavior aside from strongly admonishing the llm to not use the feature.

The end result is wasting tokens and time on incorrect default assumptions.

What steps can reproduce the bug?

Enter plan mode. Prompt with an ambigious plan that requires asking a question. Ignore for two minutes. Observe that planning proceeded anyways.

What is the expected behavior?
