Software	version
buble	0.19.8

Input:

setState(previousState => ({
    ...previousState,
    field: {
        ...previousState.field,
      [field]: true
    }
}))

Output:

setState(function (previousState) {
    var obj;

    return (Object.assign({}, previousState,
    {field: Object.assign({}, previousState.field,
      ( obj = {}, obj[field] = true, obj )}));
})

Desired output:

setState(function (previousState) {
    var obj;

    return (Object.assign({}, previousState,
    {field: Object.assign({}, previousState.field,
      ( obj = {}, obj[field] = true, obj ))}));
//                                        ^
})
