<pre>
    Given the input C++ file:
```C++
struct A {
    A();

    std::map<int, int> m;
};

A::A() : m({
 {1, 1},
        {2, 2},
#if defined(AAA)
        {3, 3},
#endif
        {4, 4},
        }) {
}
```
After formatting by command `clang-format --style=llvm`:
```C++
struct A {
  A();

  std::map<int, int> m;
};

A::A()
    : m({
        {1, 1}, {2, 2},
#if defined(AAA)
            {3, 3},
#endif
            {4, 4},
      }) {
}
```
Expected result:
```C++
struct A {
  A();

  std::map<int, int> m;
};

A::A()
    : m({
          {1, 1},
          {2, 2},
#if defined(AAA)
          {3, 3},
#endif
          {4, 4},
      }) {
}
```
Also I have noticed that this only seems to happen with `#if`, but not `#ifdef`:
```C++
A::A()
    : m({
 {1, 1},
          {2, 2},
#ifdef AAA
          {3, 3},
#endif
          {4, 4},
      }) {
}
```
This gives the correct result as expected.
