MaybeNormalizePath is affecting Windows usecase:

base::FilePath MaybeNormalizePath(const base::FilePath& path) {
#if defined(OS_WIN)
  // Normalize any drive letter to upper-case. We do this for consistency with
  // net_utils::FilePathToFileURL(), which does the same thing, to make string
  // comparisons simpler.
  base::FilePath::StringType path_str = path.value();
  if (path_str.size() >= 2 && path_str[0] >= L'a' && path_str[0] <= L'z' &&
      path_str[1] == L':')
    path_str[0] = towupper(path_str[0]);
  return base::FilePath(path_str);
#else
  return path;
#endif
}
