Decorator emit incorrect within `try` block

[DanielRosenwasser]

function Decorator() {
    return (target: new (...args: any[]) => any) => {};
}

try {
    @Decorator()
    class MyClass {
        public static func(): MyClass {
            return new MyClass();
        }
    }
}
catch (e)
{
}

Current Emit

try {
    var MyClass_1 = /** @class */ (function () {
        function MyClass() {
        }
        MyClass_2 = MyClass_1;
        MyClass.func = function () {
            return new MyClass_2();
        };
        var MyClass_2;
        MyClass_1 = MyClass_2 = __decorate([
            Decorator()
        ], MyClass_1);
        return MyClass;
    }());
}
catch (e) {
}

Expected Emit

try {
    var MyClass = /** @class */ (function () {
        function MyClass() {
        }
        MyClass_1 = MyClass;
        MyClass.func = function () {
            return new MyClass_1();
        };
        var MyClass_1;
        MyClass = MyClass_1 = __decorate([
            Decorator()
        ], MyClass);
        return MyClass;
    }());
}
catch(e) {
}

The issue is that the MyClass_1 argument in the __decorate([..]) function call is undefined.

The expected emit should be similar to the emit without the try/catch block:

try {
    var MyClass = /** @class */ (function () {
        function MyClass() {
        }
        MyClass_1 = MyClass;
        MyClass.func = function () {
            return new MyClass_1();
        };
        var MyClass_1;
        MyClass = MyClass_1 = __decorate([
            Decorator()
        ], MyClass);
        return MyClass;
    }());
}
catch(e)
{
}
