Issue Type: Bug

Does this issue occur when all extensions are disabled?: Yes

Windows 11 has these snazzy new rounded borders that are interfering with the window.activeBorder setting in settings.json.

Back on Windows 10 these settings worked fine: my window's border was set to the color indicated.

workbench.colorCustomizations": {
        // Default border windows (since I mostly like dark themes)
        "window.activeBorder": "#66ffff",
        "window.inactiveBorder": "#fcfcfc",
        // Some dark/light window borders, in case I delete/lose the above ones:
        "[Solarized Dark]": {
            "window.activeBorder": "#66ffff",
            "window.inactiveBorder": "#fcfcfc"
        },
        "[Solarized Light]": {
            "window.activeBorder": "#000000",
            "window.inactiveBorder": "#737373"
        },
        "[Base16 Ocean Deep]": {
            "editorError.background": "#7c0b0b8c",
            "editorError.foreground": "#ffffff"
        }
    },

On Windows 11 VSCode is trying to set the border color, but Win11's rounded window edges appear to be obscuring it in an unpredictable pattern:

To reproduce:

1. edit settings.json to include the above snippet.

2. Resize the window to make it smaller

3. Notice that the window borders are NOT the indicated color
   

4. Resize the window to make it bigger

5. Notice that the window border DOES change, but only on the bottom and right edges:
   

Here's an animated gif showing the unpredictable nature of the border-hiding:
