"toggleSettings" doesn't seem to work with objects

This :

...
    "files.exclude": {
        ".*": true
    },
    "commands.commands": {
        "Toggle hidden files": {
            "command": "commands.toggleSetting",
            "args": {
                "setting": "files.exclude",
                "value": [
                    {
                        ".*": true
                    },
                    {
                        ".*": false
                    }
                ],
            }
        }
    },

doesn't work as intended. The setting is not changed.
However, using the command as set/reset with only one value works as intended.
