control flow flattening with class declaration producing runtime error

[sanex3339]

Following code will produce runtime error after obfuscation:

(function(){
    class Test1 {
        foo () {
            var that = this;
            
            console.log(that.foo + '');
        }
    }
    
    class Test2 {
        bar () {
            var that = this;
            
            console.log(that.bar + '');
        }
    }

    console.log(new Test1().foo());
    console.log(new Test2().bar());
})();

Control flow flattening will wrap all statements into switch-case statement, but ClassDeclaration node scope is CaseStatement, so in other CaseStatement this class will undefined
