Extra Enter(New Page) is getting added after page break when i remove the next sibling node

I’ve attached the document containing the code for your review.

There are two content controls in the document. When I remove the last content control, an extra page is added after the page break in the first content control due to an additional line break after page break.

@mohitkumar1991 The behavior is expected. If you remove the paragraph in MS Word, you will get exactly the same result. Page break in MS Word document is a child of paragraph so there always will be paragraph break after page break, though there might be some text after page break, but anyways there will be paragraph break at the end.
