Section header text appearing one page early in a specific situation












0















Due to specific reasons, I created an alternative section command called nsection. The simplified version below should behave similarly to the original section command, however, I get an unexpected behavior regarding the header text.



When I use nsection at a place where page-break occurs, the header text appears one page too early. In the example below, the title D header should appear only on page 4, but it appears already on page 3. Apparently, the original section command does something to prevent this behavior, as the title C header does not appear on page 2.



I am interested in knowing why this happens and how to configure my custom command to prevent it.



I realized, that calling clearpage before my nsection solves the issue, however, this would result in unwanted behavior if placed anywhere but the page break.

DeclareDocumentCommand{nsection}{oom}{%

fancyhead[RE,LO]{sffamily slshape #3}
