Per inspection result from above comment, the behavior is actually a bug in the upstream v4l2loopback source, function v4l2_loopback_write:

  /* there's at least one writer, so don'stop announcing output capabilities */
  dev->ready_for_output = 0;

Which set `dev->ready_for_output` to zero without correcting its `dev->type`.
