Just want to mention that VSCode actually let's the user decide, see my post in the previous discussion.
To me, the general question is: "When do people look at the window title?"
Personally, I only "see" the window title in a taskbar or when Alt + Tabbing between different windows. I.e. when trying to change to some window that is not currently visible on screen. In this view, the window title is always truncated in some way, so displaying just the note title as first information would make most sense.
