Bug or Feature: Changes to Window Reopen Behavior in macOS 26

Since macOS 26 Beta 1, I notice that the window reopening behavior had changed.

Say there are two desktops (spaces), one might:

1. open an app window in desktop 1
2. close that window
3. switch to desktop 2
4. reopen the app window (by click on dock tile, spotlight search...)

Prior to macOS 26, that window will always reopen in current desktop. This is IMO the right behavior because these windows are most likely transient (message app, chat app, utilities app or note app).

In macOS 26, however, will switch to desktop 1 (where the window is closed) and reopen the window in desktop 1.

This is weird to me because:

• Window is "closed", hence it should not be attached to desktop 1 anymore, unlike minimize.
• Switching desktop interrupts user's current workflow. It's annoying to switch back specially when there're many desktops.
• This behavior is inconsistent. Some reopen in current desktop, some reopen in previous desktop. Apps like Music, Notes and Calendar reopened in previous desktop, while Mail, Messages, and Freeform reopened in current desktop.

I did a little bit of experiment, and find out that apps that reopened in current desktop are most likely because they take an extra step to release the window when it's closed.

I believe this is a bug, so I fire a feedback (FB18016497) back in beta 1. But I did not get any response or similar report from others, to a point that I kinda wonder if this is intended.

I can easily force my app to reopen in current desktop by nullifying my window controller in windowWillClose, but this behavior essentially change how one can use the Spaces feature that I think I should bring this up to the community and see what other developers or engineers thinks about it.
