Steps to reproduce:
1. Open the attached “IN-142442_AssistantTest.zip” project
2. Open the “SampleScene” Scene
3. Make changes to the Scene so it becomes dirty
4. Open Tools → Save Open Scenes
5. Observe the Console

Actual result: SaveOpenScenes returns true
Expected result: SaveOpenScenes returns false

Reproducible with: 2023.1.0a3, 6000.0.75f1, 6000.3.15f1, 6000.4.7f1, 6000.5.0b8, 6000.6.0a5

Reproducible on: macOS Sequoia 15.7.5 (M1 Max)
Not reproducible on: No other environments tested

Notes:
-The project is set up so saving the scene is impossible
-Documentation states that SaveOpenScenes() returns true if all open Scenes are successfully saved
