Allow validation on nested relational values through parent validation settings

[ananth3087]

Describe the Bug

When we configure the validation for child data model from parent data model using validation tab and then its not working in latest version ( 9.21.2), but it was working in old version like 9.10.0.

Note: I dont want to configure the validation in Child data modal because i planned to create multiple relationship field with same Child data modal, so each time, i will use different validation rules, so Parent is the better place to configure it.

• I have created two entity such as Parent and Child.
• I have related the Parent and child using Many to many relationship.

Parent Entity with Many to many relationship with child:

Child Entity:

In parent, we child field (many to many field), and then there is a validation tab in which i have configure the validation for field in child, but its not working.

In following screenshot, you can see that i'm able to create child with empty title

To Reproduce

We can use latest version above 9.12 to reproduce this issue.

• I have created two entity such as Parent and Child.
• I have related the Parent and child using Many to many relationship.

Parent Entity with Many to many relationship with child:

Child Entity:

In parent, we child field (many to many field), and then there is a validation tab in which i have configure the validation for field in child, but its not working.
