t.start()KernelRuntimeContext associated with it and it still has the same Stdout objectconsole_output_worker that has some timing loop associated with it, but it's not clear to me why it would print to console instead of just dropping the outputs: https://github.com/marimo-team/marimo/blob/01c1745634ede31b419e70ef484d34e128192033/marimo/_messaging/console_output_worker.pymo.Thread is initialized with the parent thread's context, but I believe it needs its own context. What's happening now is that after the cell that creates the mo.Thread finishes executing, the parent thread's Stdout is correctly disconnected from the cell, but this disconnects the mo.Thread's Stdout too.Stdout and Stderr objects redirected, similar to this: https://github.com/marimo-team/marimo/blob/b9402ce516dd102464fe5a3cb75a979dc8179cc0/marimo/_runtime/runtime.py#L648-L654. You can use the cell_id of the parent thread's context. But you likely don't want to use redirect_streams as a context manager, since they should be permanently redirected.
