workbench.colorCustomizations for window.activeBorder & window.inactiveBorder not working

[pasisavolainen]

Type: Bug

settings.json:

{
    "workbench.colorTheme": "Default Dark+",
    "window.titleBarStyle": "custom",
    "workbench.colorCustomizations": {
        "window.titleBarStyle": "custom",
        "window.activeBorder": "#00ff4c",
        "window.inactiveBorder": "#2d03eb"
    },
}

Neither active/inactive border colors work. Both August-22(1.71)/Insiders versions affected. I'm pretty sure I saw the colors working in version I had installed previous to August (Probably 1.70).

VS Code version: Code - Insiders 1.72.0-insider (d17726f, 2022-09-05T05:18:01.077Z)
OS version: Windows_NT x64 10.0.19044

Support for window border was pulled out for Windows beginning with 1.71.x version. We enabled window control overlays and window borders do not work well in combination. Besides, borders were never fully working depending on window zoom levels and screen DPI. As such, there is #153222 for supporting a native window border from the OS that is not done by CSS from inside the window.
