What issue are you seeing?

Since recent releases the loading animation is broken when starting codex with a direct inline start prompt:

e.g. '• Working (1s • esc to interrupt)' is not shown anymore when starting codex like this: codex 'build an xmas tree'

What steps can reproduce the bug?

To reproduce in Ghostty

codex 'build an xmas tree'

no loading spinner shows:

When starting codex directly and prompting manually:
codex -> then type the prompt manually

loading spinner shows perfectly

What is the expected behavior?

The loading animation should also show with an initial prompt: '• Working (1s • esc to interrupt)'
