Issue with Annotation Merging in Schema Using Effect Library

import { Effect, Schema, SchemaAST } from "effect";

const AccountNumber = Schema.NonEmptyString.annotations({
  examples: ["1300"],
  title: "Konto",
  description: "Konto",
});

const SomeSchema = Schema.Struct({
  number: AccountNumber,
}).annotations({
  title: "Foo",
  identifier: "Should be kept",
});

const SomeOtherSchema = SomeSchema.annotations({
  title: "Bar",
});

const a1 = SchemaAST.getIdentifierAnnotation(SomeSchema.ast); // Some
const a2 = SchemaAST.getIdentifierAnnotation(SomeOtherSchema.ast); // None

console.log({ a1, a2 });
