Enum type checking seems broken

TypeScript Version: 3.7.x-dev.201xxxxx

Search Terms:
Enum, enum type checking, enum param
Code

enum MyEnum {
	B = 3
}

function foo(param: MyEnum) {    
}

foo(MyEnum.B); // This should be the only working example.

foo('asdfasdf'); // This does not work, which is good.

foo(2); // This should also not work, but it does. :(

Expected behavior:
foo(2) - should result in TS: 2345 argument of type number is not assignable to a parameter of type MyEnum..
Actual behavior:
No errors.

Playground Link: demo
Related Issues: None.

I think the actual behaviour of TS makes using enums almost pointless to me. If I want a stricter type checking I have to manually create an union type or a function which returns union types.
