Extended class does not satisfy requirement when defining default data without explicit type

[OrkhanAlikhanov]

TypeScript Version: 3.5.3

Code

class Route {
  method: 'get' | 'post';
}

class MyRoute extends Route {
  method = 'get' // error?
  // method: 'get' = 'get' // compiles fine
}

Expected behavior:
Should compile fine by inheriting same type from base abstract class

Actual behavior:
Getting error:

TS2416: Property 'method' in type 'MyRoute' is not assignable to the same property in base type 'Route'.
Type 'string' is not assignable to type '"get" | "post"'.
