Visual Studio Code: ignore language specific setting on sync

I want to exclude a language specific setting in Visual Code from syncing. I already have excluded a non-specific setting, which works correctly:

"editor.rulers": [
    80
],
"settingsSync.ignoredSettings": [
    "editor.rulers",
]

However, I also have set this setting for a specific language:

"[python]": {
    "editor.rulers": [
        88
    ]
}

This setting still gets synced. How can I exclude this as well?
