AutoPlaceHolder with angular material mat-input not working

[fabrizziocht]

I'm trying to show the country placeholder example using matInput from angular material, but not works. I enabled autoPlaceholder = aggressive:
<input matInput type="text" ng2TelInput [ng2TelInputOptions]=" {'onlyCountries': ['pe', 'br'], 'separateDialCode': true, 'autoPlaceholder': 'aggressive'}" formControlName="tel" (hasError)="hasError($event)" (ng2TelOutput)="getNumber($event)" (intlTelInputObject)="telInputObject($event)" (countryChange)="onCountryChange($event)" >

I am using the same & able to get placeholder based on selected country. Can you provide some reproduction like provide stackblitz to show your issue?
