💻 Code

class A {
  p: true | 'string value' = true;
  o: {test: number} = {test: 1};
}

class B extends A {
  p = 'string value';
  o = {test: 5};
}

🙁 Actual behavior

Error when overriding the p property:

Property 'p' in type 'B' is not assignable to the same property in base type 'A'.
  Type 'string' is not assignable to type 'true | "string value"'.

🙂 Expected behavior

No errors, since the code is correct and types are respected
