SequenceGenerator not working in MappedSuperclass

[mgiraud]

Bug Report

Q	A
Version	3.6.2

Summary

A SequenceGenerator defined in the MappedSuperclass does not modify the generated sequence name.

How to reproduce

MappedSuperClass

#[ORM\MappedSuperclass]
class ParentSuperclass
{
    #[ORM\Column(name: "id_parent", type: Types::INTEGER)]
    #[ORM\Id]
    #[ORM\GeneratedValue(strategy: "SEQUENCE")]
    #[ORM\SequenceGenerator(sequenceName: 'seq_id_parent')]
    protected ?int $id = null;
}

Child

#[ORM\Entity]
#[ORM\Table(name: 'child')]
class Child extends ParentSuperclass
{}

doctrine:schema:update --dump-sql

CREATE SEQUENCE child_id_parent_seq INCREMENT BY 1 MINVALUE 1 START 1;
CREATE TABLE child (id_parent INT NOT NULL, PRIMARY KEY (id_parent));

This can be worked around by moving the $id property with attributes to the Child class.
