Describe the bug

When querying an entity with relations, the Model hiddenProperties is not respected for the relation entities 1 or more levels deep.

loopback-next/extensions/sequelize/src/sequelize/sequelize.repository.base.ts

Lines 1074 to 1076 in 3f0869c

	let parentEntityInstances = parentEntities.map(
	sequelizeModel => new this.entityClass(sequelizeModel.toJSON()) as T,
	);

Relation types that are including hidden properties:

• belongsTo
• hasMany
• hasManyThrough
