What issue are you seeing?

During a multi-turn browser workflow, an agent-created Chrome tab closed automatically when a turn ended. Chrome restored the tab, but the external form’s in-progress state was lost. Recovery required user supervision and repeating a CAPTCHA.

What steps can reproduce the bug?

1. Start a multi-turn browser workflow that creates a Chrome tab.
2. Leave the workflow unfinished at the end of a turn.
3. Allow the turn to end.
4. Observe that the agent-created tab closes.
5. Restore the tab in Chrome and observe that the form state is not preserved.

What is the expected behavior?

Unfinished agent-created tabs should remain available across turn boundaries, or their state should be preserved with a clear warning before closure.

Additional information

Prepared by Codex at the user’s request. No credentials or identifying information are included.

Reproduce the multi-turn browser workflow described on Darwin with an agent-created Chrome tab, then trace what happens when the turn ends. Check the tab lifecycle and recovery behavior; done means unfinished tabs remain available across turns or the user receives a clear warning and the external form state is preserved.
