[Bug] SetValidator appears to take no effect

[pingu2k4]

Describe the bug
When using SetValidator on a list of items, it appears to not be used. Whereas replicating the same rules within ChildRules does work.

To Reproduce
Steps to reproduce the behavior:

1. Create an object with a list of T
2. Create a validator for T, which a rule you can easily attempt to break
3. Create a form using the object with a list of T, and hook up the validation as well as the ability to create items and "break" the rule
4. attempt to submit and notice that validation passes, and OnValidSubmit triggers
5. Recreate the same rules within ChildRules
6. Try again and notice that OnValidSubmit does not trigger.

Expected behavior
Identical rules within ChildRules and SetValidator should behave identically

Screenshots

Hosting Model (is this issue happening with a certain hosting model?):

• Blazor WebAssembly

Additional context
I am using the following rules. The ModifyEmployeeModelRoleValidator has rules identical to those inside ChildRules. If I comment out the ChildRules part, then validation succeeds, incorrectly.

RuleForEach(x => x.Roles).SetValidator(new ModifyEmployeeModelRoleValidator());
RuleForEach(x => x.Roles).ChildRules(role =>
{
    role.RuleFor(x => x.Level).GreaterThanOrEqualTo(x => x.MinLevel)
        .When(x => x.MinLevel is not null, ApplyConditionTo.CurrentValidator)
        .LessThanOrEqualTo(x => x.MaxLevel - 1)
        .When(x => x.MaxLevel is not null, ApplyConditionTo.CurrentValidator);
});
