Steps to reproduce.
- Split scene into 3 parts
- Rearange the parts
- Select all three parts in Binder
- From Documents menu select Merge documents.
Result new document loses margin on left and right and text is butted up to edge of the active editor area.
Expect: Margin to stay the same after merge.
When viewing the chapter in Scrivenings view with other scenes that have the correct margin, the text in the merged scene visually adopts the correct margin of the other scenes but with the ruler on, the markers are still at the extreme left and right for that scene.
