Ion-toast - Message with ion-icon

Ionic Framework
1 
  async presentToast(): Promise<void> {
    const toast = await this.toastController.create({
      message: 'Install this PWA on your iPhone: Tap <ion-icon name="share" color="warning" size="large"></ion-icon> icon bellow and Add to Home Screen ',
    });
    toast.present();
  }

It’s not working because sanitization made on message toast not allow color and size attributes. It also do not work when the name of ion-icon contains a slash like:

<ion-icon name="share-social"></ion-icon>

Any help on this?
