Depend Form.Item validation ignore Form.validationTrigger="onSubmit"

[POSTAL5532]

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

1. set Form validationTrigger = "onSubmit"
2. add 2 fields to the form, the second field must be dependent on the first (<Form.Item name="secondItem" dependencies={["firstItem"]}>...</Form.Item>)
3. add a validation rule for the 2nd field (for example "required")
4. enter and then delete data in the second field
5. enter data in the first field

What is expected?

Validation for the second field is triggered only after submitting the form

What is actually happening?

Validation for the second field is triggered immediately after editing the first field (provided that the first field was touched)

If this behavior is initially valid, then it would be more logical to allow control over the validation of dependent fields using the 'validateTrigger' parameter in the Rule object, which will take precedence over the 'validateTrigger' parameter in the Form.
