clang-format c code - Incorrect formatting of else if over conditionally compiled code

[isolansky]

code:

while (true) {
#if DEF_SET_ANOTHER
    if (var == 1) {
        ;
    } else
#endif /* DEF_SET_ANOTHER */
        if (var == 3) {
        ;
    } else if (var == 4) {
        ;
    } else if (var == 5) {
        ;
    }
};

Issue is obvious, it formats following code differently

Smaller repro with LLVM style:

#if SOMETHING
if (var == 1) {
} else
#endif //
  if (var == 2) {
  } else if (var == 3) {
  }

or

#if SOMETHING
if (var == 1) {
} else
#endif /**/
  if (var == 2) {
  } else if (var == 3) {
  }

But without comment on #endif, it's ok:

#if SOMETHING
if (var == 1) {
} else
#endif
    if (var == 2) {
} else if (var == 3) {
}
