VSCode context menu appears in the wrong window when stacked

[Aqa-Ib]

I am experiencing an issue where the context menu in VSCode always appears in the wrong instance when multiple VSCode windows are stacked in COSMIC. If I right-click in any instance, the context menu consistently opens in the last opened instance of the program, regardless of which window I right-click in. This issue does not occur if the VSCode instances are not stacked. The behavior suggests a problem with COSMIC stacked windows + Electron popups, because it does not occur with Qt, Gtk nor Iced; and it does not happen on Sway (but it also happens on Hyprland).

How to reproduce:

• Ensuring VSCode is running natively under Wayland
• Open two or more instances of VSCode.
• Create a stack with the VSCode windows together.
• Right-click in any window other than the last opened instance.
• Observe that the context menu opens in the last instance of VSCode, not the window where the right-click occurred.

Cheers !
