The `NgControlStatusGroup` directive is shared between template-driven and reactive form modules. In cases when only reactive forms module is present, the `NgControlStatusGroup` directive is still activated on all `<form>` elements, but if there is no other reactive directive applied (such as `formGroup`), corresponding `ControlContainer` token is missing, thus causing exceptions (since `NgControlStatusGroup` directive relies on it to determine the status). This commit updates the logic to handle the case when no `ControlContainer` is present (effectively making directive logic a noop in this case). Alternative approach (more risky) worth considering in the future is to split the `NgControlStatusGroup` into 2 directives with different set of selectors and include them into template-driven and reactive modules separately. The downside is that these directives might be activated simultaneously on the same element (e.g. `<form>`), effectively doing the work twice. Resolves #38391. PR Close #40344
