### Current Behavior

I'm executing a state machine using the following definition:

```json
{
  "StartAt": "Parallel",
  "States": {
    "Parallel": {
      "Type": "Parallel",
      "Next": "Unreachable",
      "Branches": [
        {
          "StartAt": "Fail",
          "States": {
            "Fail": {
              "Type": "Fail"
            }
          }
        }
      ]
    },
    "Unreachable": {
      "Type": "Pass",
      "Parameters": {
        "UnreachableOutput": true
      },
      "End": true
    }
  }
}
```

The execution is a success with the following output:

```json
{
   "UnreachableOutput": true
}
```

### Expected Behavior

The execution should fail.

On AWS executing a state machine using the provided definition results in an error. The execution should fail before reaching the state named `Unreachable` because an error occurred in one of the branches of the preceding Parallel state.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

Create and execute a state machine using the provided definition.

### Environment

- LocalStack: 3.0.3.dev20231207105008
