Incorrect select when selecting an embedded property from a joined entity if prefix is set to false

[dirslashls]

Describe the bug
The following code generates incorrect SQL

		const query = em.qb(TestB,'b')
				.leftJoin('b.a','a')
				.select(['b.*','a.name'])
				.getQuery();
		console.debug(query);

select `b`.*, `b`.`name` from `test_b` as `b` left join `test_a` as `a` on `b`.`a_id` = `a`.`id`

Instead of a.name , the SQL is generated with b.name. Here a.name is from an embedded entity with prefix set to false.

To Reproduce
Steps to reproduce the behavior:

Below are the entity definitions.

@Embeddable()
class TestNamedEntity {
	@Property({ length: 100 })
	name!: string;

	@Property({ length: 250 })
	description!: string;
}

@Entity()
class TestA {
	@PrimaryKey()
	id: number;

	@Embedded({ prefix: false })
	identity: TestNamedEntity;
}

@Entity()
class TestB {
	@PrimaryKey()
	id: string;

	@ManyToOne('TestA',{ cascade: [] })
	a?: Ref<TestA>;
}

Expected behavior
The SQL should be

select `b`.*, `a`.`name` from `test_b` as `b` left join `test_a` as `a` on `b`.`a_id` = `a`.`id`

Additional context
This happens with prefix = false.
