Issue with Stage Manager Functionality in Coherence Mode

I'm experiencing an issue with Stage Manager functionality when using multiple instances of Windows applications in Coherence mode. The details of my setup and the problem are as follows:
System Information:
  • MacOS Version: 15.0.1 (24A348)
  • Parallels Desktop Version: Version 21.0.0 (55732)
  • Windows Version: Version 10.0.22631 Build 22631
  • Coherence Mode: Enabled
  • Stage Manager: Enabled
Issue Description:
  1. When using a single instance of a Windows app in Stage Manager, everything works as expected.
  2. Problems occur when using multiple instances of the same Windows app (e.g., two Windows Explorer windows) side by side in Stage Manager:
    - Initially, both instances appear and function correctly.
    - However, when Stage Manager switches to other apps and I bring back one of the Windows app instances, both appear side by side, but:
    - Clicking on one instance acts as if I'm clicking on the desktop.
    - This action closes both instances of the app.
    - It's always unclear to me which one will do this; sometimes it's the left, other times it seems the right.
  3. This issue only affects Windows applications. Multiple instances of macOS apps (e.g., Safari) work correctly in Stage Manager.
Steps to Reproduce:
  1. Open two instances of a Windows app (e.g., Windows Explorer) in Coherence mode.
  2. Arrange them side by side using Stage Manager.
  3. Switch to a different app using Stage Manager.
  4. Bring back one of the Windows app instances.
  5. Attempt to interact with either instance of the Windows app.
  6. If it happens to work, repeat and try the other instance.
Actual Behavior:
Clicking on a second instance of the Windows app acts as if clicking on the desktop, closing both instances.
