 - 쪽 수 추정이 글 뒤에 둔 어울림(`textWrap="SQUARE"`) 개체의 자리가 문단 둘째 줄 이후에 오는 경우도 따른다. 한/글처럼
   문단을 단 폭 그대로 나눴을 때 그 자리가 든 줄을 찾고, 개체를 그 줄 위에서부터 놓는다. 그 앞 줄은 단 폭 그대로이고,
   그 줄부터 개체 곁으로 좁아진다. 전에는 첫 줄에 드는 경우만 따르고 나머지는 지원하지 않았다.
+- 위의 어울림 개체 자리가 앞 줄을 꼭 채운 바로 뒤(다음 줄의 시작)에 오면, 한/글처럼 그 글이 끝나는 앞 줄에 든 것으로 센다.
+  예를 들어 첫 줄을 꼭 채운 글 뒤의 개체는 문단 위에서부터 놓인다. 전에는 줄 배치 정보가 없는 문서에서 다음 줄에 든
