Bug
In the Cowork "new task" composer, typing a message and trying to submit it always reopens the "Select repo..." picker overlay instead of sending.
Repro steps
- Open a new Cowork task
- Click into the message field, type a message (e.g. "test")
- Press Enter -> "Select repo..." overlay pops up instead of sending
- Click the send arrow icon instead of pressing Enter -> same overlay reopens, message still not sent
- Explicitly selecting a repo from the dropdown (or clicking "Default") -> [describe what happens: does overlay still reopen?]
Expected
Pressing Enter or clicking send should submit the message and start the task.
Actual
Repo picker overlay reopens every time, blocking task submission entirely.
Environment
- Model: Fable 5, High reasoning
- Screenshot attached showing composer with "test" typed and repo picker open
