Context doesn't allow access to nested data

[tomaszkane]

What steps will reproduce the problem?

public function getRules(): array
{
 return [
 'submitForVerification' => [
 new Required,
 new BooleanValue,
 ],
 'tasks' => [
 new Each(
 new Nested([
 'push' => [
 new Nested([
 'isEnabled' => [
 new Required(when: fn() => $this->submitForVerification),
 new BooleanValue,
 ],
 'content' => [
 new Required(when: [???]),
 ],
 ])
 ],
 ])
 )
 ],
 ];
}

What is the expected result?

I can set Required validator for content dependent on his sibling isEnabled value.

What do you get instead?

It cannot be done? Or it'll be ugly solution.
