I would say do not worry about it. Eight lines is not a large or small amount of "extra space", and it should not impact the rest of the book. However, if you want to fit everything onto the previous page to conclude the chapter, then you could try doing some extra editing to make it work out that way. Otherwise, if the current content fits the chapter like a glove, then keep everything as is!
Best of luck with your editing!
