Description

After updating from 3.94 to 3.98, tui-segmented component started throwing the following error on initialization

ERROR TypeError: Cannot read properties of undefined (reading 'valueChanges')

Stack trace leads to the following code

// node_modules/@taiga-ui/cdk/fesm2015/taiga-ui-cdk-observables.js
function tuiControlValue(control) {
  return new Observable((subscriber) => {
    if (!control.valueChanges) { // <--
      throw new TuiValueChangesException();
    }
    return control.valueChanges.pipe(startWith(control.value)).subscribe(subscriber);
  });
}

May be caused by #9074?

Taiga UI version

3.98.0

Optional chaining should be added for this case
