Ionic-framework: onWillDismiss() not called in stacked Modal Controllers

Current behavior:

onWillDismiss() not called in Modal Controller created by another Modal

Expected behavior:

onWillDismiss() gets called

Steps to reproduce:
[Sorry I don't know how to use Plunker yet]
Page A: create instance of Page B via Modal Controller
Page B: create instance of Page C via Modal Controller:

let modal = this.modalCtrl.create(CPage);
    modal.present();
    modal.onWillDismiss((data: any) => {
      console.log("CPage dismissed");
      if (data) {
        // returning data from Modal Controller
        ...  
      }
    });

the onWillDismiss() never gets called, after C is dismissed.

Other information:

1. onDidDismiss() somehow works in this situation.
2. non-stacked Modal, everything is fine. E.g. Nav Controller calls Modal
3. this issue may be related to another issue, but with PopOver instead: https://github.com/driftyco/ionic/issues/9735

Just ran into this. I believe the bug is here. Because there is an enteringView (the modal underneath the one that's being dismissed), it acts like the dismissed modal isn't unloading when it actually is. This bypasses the onWillDismiss callback here.
