### Bug Description

When i try to use fill locale from another locale i try to save the document without selecting the website locale field even though it's a required field.The filled contents are disappeared from the document and showing the error msg "Website locale is a required field"  and this is a custom validation function handled in strapi lifecycles

```
async beforeCreate(event) {
    const { params } = event;
    const { data } = params;
    if (!data.website_locale) {
        throw new ValidationError("Website locale is a required field.");
    }
  },
 async beforeUpdate(event) {
    const { params } = event;
    const { data } = params;
    const id = params?.where?.id;
    if (!data.website_locale) {
        throw new ValidationError("Website locale is a required field.");
    }
  }

```

### Steps to Reproduce

1.You have a content in English(en) locale already
2.create another version of the same content in Italy(it-IT) locale by using fill in
3.Now you use Fill in locale from english(en) and you will see the contents are populated in the input fields
4.Now you can remove the content in any required field and try to save the content.
5.Here i was using custom validation using strapi lifecycle hook
6.Validation msg will be showing "Pease select the filed before saving/publishing"
7.At the Same time the populated data's  in the input fields is cleared

### Expected Behavior

While i use fill in from another locale and before saving if it's a required field the validation will be happen and then the content should not disappeared from the fields.
