What issue are you seeing?

I use a fixed set of pre-created worktrees of my repo, with each worktree set up as a separate "project" in the Codex app. When I go to start a new thread in one of those worktree "projects", I usually update the branch checked out in the worktree first, to the branch that I want to work on / review. But when I go to create a new thread in the Codex app, the branch indicator in the lower right (below the text entry box) is more often than not stale (reflecting some branch that was previously checked out in that worktree, but not the currently checked out branch), and I have to manually select the right branch before starting the thread. Sometimes there is no branch shown there at all, which means I'm lacking the UI affordance to even select a branch. I so far haven't been able to figure out any correlations as to when the branch is missing vs shown.

What steps can reproduce the bug?

1. Create a new worktree of a git repository, and set up that worktree as a project in the Codex app.
2. Check out a new branch in that worktree.
3. Click the "Start a new thread in..." button in the left sidebar for that project.
4. The branch indicator in lower right may be missing entirely, or show a branch that isn't the currently checked-out branch.

What is the expected behavior?

The behavior I'd hope for is that the currently-checked-out branch is always consistently shown in the UI.
