Formatter moves inline comment in external declaration

[munificent]

Given this (sanitized) input:

class AaaaAaaaa {
  external Aaaaaa get aa;
  external Aaaaaa get aaAaa;
  external Aaaaaa get aa;
  external aaaa get aaaa;
  external /*AaaaaaAaaa*/ aaa get aa;
  external Aaaaaa get aaa;
}

The formatter outputs:

class AaaaAaaaa {
  external Aaaaaa get aa;
  external Aaaaaa get aaAaa;
  external Aaaaaa get aa;
  external aaaa get aaaa; /*AaaaaaAaaa*/
  external aaa get aa;
  external Aaaaaa get aaa;
}
