bug

What is the current behavior?
if an class extends another class and has the same names for something like an getter / setter, then the bottom-most class's getter / setter is used

If the current behavior is a bug, please provide the steps to reproduce.
(Typescript)

// NodeJS: 12.16.2
// MongoDB: 4.2-bionic (Docker)
import * as mongoose from "mongoose"; // mongoose@5.9.10

class C1 {
  public get hello() {
    return 1;
  }
}

class C2 extends C1 {
  public get hello() {
    return 2;
  }
}

(async () => {
  await mongoose.connect(`mongodb://localhost:27017/`, { useNewUrlParser: true, dbName: "mongooseLoadClassInheritance", useCreateIndex: true, useUnifiedTopology: true });

  const C1Schema = new mongoose.Schema({});
  C1Schema.loadClass(C1);
  const C1Model = mongoose.model("C1", C1Schema);
  console.log("C1Model", ((new C1Model()) as any).hello); // expected: "1", result: "1"

  const C2Schema = new mongoose.Schema({});
  C2Schema.loadClass(C2);
  const C2Model = mongoose.model("C2", C2Schema);
  console.log("C2Model", ((new C2Model()) as any).hello); // expected: "2", result: "1"

  await mongoose.disconnect();
})();

What is the expected behavior?
to use the top-most class's getter/setter-

Confirmed that this is already fixed, added a test in #8892

for anyone coming across this issue, i think it meant instead of 8892 to be #8897

also, this issue was fixed when #9975 got reported in 0f80ef8 (included in version 5.11.19)
