Description:
When endnotes overflow the last "content" page of a section, field variables for chapter information (name or number) show the first outline level-1 data instead of the current "chapter".

Whether the intended level-1 paragraph is inside or just before the section is irrelevant: the bug occurs the same.

Steps to Reproduce:
1. Enable page header
2. Insert"chapter name/number* in header
3. Enter a first chapter (an *Heading 1* paragraph is sufficient
4. Enter a second chapter
5. Create a section with *Collect end notes at end of section* ticked
6. Enter text with enough notes so that they cross a page boundary (including remaining space at end of section content


Actual Results:
Page header for section contents reflects the current chapter name and number. When page boundary is reached for endnotes, all subsequent pages show chapter name and number of first *Heading 1* paragraph (more precisely of first level-1 outline paragraph).

Expected Results:
Page style is the same before and after the page break between the end of section contents+first endnotes and the subsequent notes, header should remain the same.


Reproducible: Always
