One to many: Create new fails if related many to one is required

[Dominic-Marcelino]

Describe the Bug

Let's create a "parent" and a "child" collection.
The child collection get's a many-to-one relation to the parent and the parent a related one-to-many alias.

When we try to create new child items from the parent's object, the childs "parent" field is always disabled in the drawer.
On creating the item it get's automatically set to the current opened parent (everything as expected).

But once we make the parent-id field required on the child we can't create any child-items from the parent anymore. The app prevents this, as there's no parent selected.

To Reproduce

@ see above

1.) Create child and parent collection
2.) Create many-to-one relation on child to parent & corresponding one-to-many alias
3.) Create a parent object and try to create a child --> everything works as expected
4.) Set the parent_id on the child as required
5.) Re-try to create a child from the parent and it fails

Errors Shown

the parent.id field is required

It is failing again in v9.16.1, I've been waiting 2 week to be able to create O2M records.
