1. Minimal reproduce step (Required)

func (b *Builder) initMisc(dbInfos []*model.DBInfo, policies []*model.PolicyInfo, resourceGroups []*model.ResourceGroupInfo) {
	info := b.infoSchema
	// build the policies.
	for _, policy := range policies {
		info.setPolicy(policy)
	}

	// build the groups.
	for _, group := range resourceGroups {
		info.setResourceGroup(group)
	}

	// Maintain foreign key reference information.
	rs := info.ListTablesWithSpecialAttribute(ForeignKeysAttribute)
	for _, db := range rs {
		for _, tbl := range db.TableInfos {
			info.addReferredForeignKeys(model.NewCIStr(db.DBName), tbl)
		}
	}
}

ListTablesWithSpecialAttribute uses V1 and doesn't get the foreign key tables.
