Epigraph 및 titlesec+titletoc은 잘못된 행동을 만듭니다.

Question

나는 titlesec과 titletoc을 사용하여 장 제목 뒤에 minitoc을 포함하는 나만의 장 스타일을 만듭니다. 그리고 장 제목 앞에 에피그래프를 추가하고 싶을 때 에피그래프를 사용합니다.

나는 현재 여러 섹션을 포함하는 장을 작성 중이므로 minitoc은 다음 페이지에서 계속되어야 합니다. 이로 인해 비문이 잘못 인쇄되고 다음 예에서는 마지막 부분이 인쇄되지 않습니다.

내가 얻은 결과는 다음과 같습니다.

님의 답변 덕분에egreg, 제 생각에는 비문을 인쇄하는 데 필요한 페이지가 종료되는 것과 관련이 있는 것 같은데 어떻게 해결해야 할지 모르겠습니다.

도움을 주셔서 감사합니다.
