Fetch EAGER ManyToOne nullable relation cannot be nulled during PUT or PATCH operation

[ambroisemaupate]

API Platform version(s) affected: 3.2.16

Description

Entities with ORM\ManyToOne(fetch: 'EAGER') nullable relation can be setted during a PUT or PATCH with an IRI, but cannot be nulled.

If I remove fetch: 'EAGER', I can set relation to null.

How to reproduce

With EAGER fetch

#[ORM\ManyToOne(targetEntity: File::class, fetch: 'EAGER')]
#[ORM\JoinColumn(name:'image_id', nullable: true, onDelete: 'SET NULL')]
#[Groups(['block:read', 'block:write', 'webPage:single:read'])]
#[ApiProperty(description: 'File IRI reference', example: '/api/files/1ee8859e-d2fd-6bda-ae37-d9341637fbc1')]
private ?File $image = null;

When I inspect request in Symfony Profiler: previous_data contains an image but data too !

Without EAGER fetch

#[ORM\ManyToOne(targetEntity: File::class)]
#[ORM\JoinColumn(name: 'image_id', nullable: true, onDelete: 'SET NULL')]
#[Groups(['content:read', 'content:write'])]
#[ApiProperty(description: 'File IRI reference', example: '/api/files/1ee8859e-d2fd-6bda-ae37-d9341637fbc1')]
private ?File $image = null;

When I inspect request in Symfony Profiler: previous_data contains an image then data has null image
