Required block brackets are removed on case statements

[Domi04151309]

When rendering the following code using the formatter, it removes the brackets causing JavaScript execution to fail because of the redeclaration of a const variable.

Original Code

function loadData(data) {
  for (const [instruction, parameters] of data) switch (instruction) {
  case 'point': {
    const [vector, label] = parameters;
    CoordinateSystem.addPoint(vector, label);
    break;
  }
  case 'arrow': {
    const [start, end, label] = parameters;
    CoordinateSystem.addArrow(start, end, label);
    break;
  }
  case 'line': {
    const [start, direction, label] = parameters;
    CoordinateSystem.addLine(start, direction, label);
    break;
  }
  case 'plane': {
    const [normalVector, distance, label] = parameters;
    CoordinateSystem.addPlane(normalVector, distance, label);
    break;
  }
  default:
    console.warn('Unknown instruction type', instruction);
    break;
  }
}

Rendered Code

function loadData (data) {
	for (const [instruction, parameters] of data) {
		switch (instruction) {
			case 'point':
								const [vector, label] = parameters;
				CoordinateSystem.addPoint(vector, label);
				break;;
			case 'arrow':
								const [start, end, label] = parameters;
				CoordinateSystem.addArrow(start, end, label);
				break;;
			case 'line':
								const [start, direction, label] = parameters;
				CoordinateSystem.addLine(start, direction, label);
				break;;
			case 'plane':
								const [normalVector, distance, label] = parameters;
				CoordinateSystem.addPlane(normalVector, distance, label);
				break;;
			default:
				console.warn('Unknown instruction type', instruction);
				break;
		}
	}
}

Fixed, thank you for reporting.
