OnConflictColumns.UpdateNewValues doesn't work in MapCreateBulk

[w7089]

entity.SomeFIeld has unique index index defined. So on insert of entities with the same value of SomeFIeld, i'd expect UNIQUE constraint failed to be raised.

However, for upserts, i'd like the other columns to be overriden with the new values.

While using below code to achieve bulk insert while allowing upserts, i'm getting UNIQUE constraint failed.

_, err = dal.db.Entity.MapCreateBulk(entitiesData, func(create *ent.entityCreate, i int) {
    _, err := entityCreate.
        SetField1(entitiesData[i].some).
        ...
        OnConflictColumns(entity.SomeFIeld).
        UpdateNewValues()

}).Save(ctx)

Doing insert one by one doesn't result in this error:

for _, test := range  `entitiesData`{
    _, err := dal.db.entities.
        Create().
        SetField1(test.some)
        OnConflictColumns((entity.SomeFIeld).
        UpdateNewValues().ID(ctx)
}

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.
