Unnecessary save prompt when closing one view in split view

[CennoxX]

Description of the Issue

When working with a document opened duplicated in split view in Notepad++, if one view is closed, the software prompts the user to save changes. This behavior can be inconvenient, as the changes should only be saved when the second view is also closed.

Steps to Reproduce the Issue

1. Open Notepad++ and open a document.
2. Rightclick on document tab > Move Document > Clone to Other View
3. Make changes to the content of one view.
4. Close one of the windows.

Expected Behavior

When closing one of the duplicate windows in split view, Notepad++ should not prompt the user to save changes. The changes should only be saved when the second view is also closed.

Actual Behavior

Currently, when closing one of the duplicate views in split view, Notepad++ prompts the user to save changes, which can be inconvenient as the changes should only be saved when the second view is also closed.

@CennoxX,

I see your point.
OTOH - if you have a lot of tabs opened, you might forget the tab is duplicated and wonder why you don't get the Save prompt.
