Calling markAllAsTouched() on parent form doesn't mark ControlContainer controls as touched

[eltaro]

Which @angular/* package(s) are the source of the bug?

forms

Is this a regression?

No

Description

1. Have a component with ControlContainer that is looking at a FormGroup in the parent form.
2. From the parent component, call form.markAllAsTouched().
3. Use devtools to observe the behavior. In the actual FormGroup object, the controls are correctly marked as touched, however, in the DOM, you will be able to see the controls inside the ControlContainer component aren't touched.

You're issue is due to the OnPush strategy. CD isn't triggered on your CVA because your component isn't marked dirty in any way.

Btw if you are looking for a working for this issue,

it would be to subscribe to touchChanges via the v18 events observable and invoke markForCheck.
