ionic-framework: ionViewCanLeave lifecycle hook on Tabs page - error with ion-segments

Ionic version: (check one with “x”) [ ] 1.x [x] 2.x

Current behavior: I believe this to be a bug, although you may correct me if I am wrong: using an ionViewCanLeave() lifecycle hook on a tabs page which implements ion-segments seems to cause the ion-segment-buttons to stop operating after rejecting the promise.

E.g. I have a tab button hooked up to a logout button with an ionSelect implemented. This ionSelect fires my logout logic (which pops the page). After tapping “No” to confirm if I want to log out, the ion-segment seems to be inoperable.

This seems to be the case when the hook is implemented on the main tabs TypeScript file.

Expected behavior: For the ion-segment to continue working, after rejecting the promise returned in ionViewCanLeave.

Steps to reproduce:

1. Clone the following repository: https://github.com/kelvindart/ionic2-tabs-lifecycle.
2. mkdir www so Ionic/Cordova recognises it as a Cordova project.
3. Run npm install.
4. Run ionic serve.
5. Tap “Go to Tabs”.
6. Tap “Log out”.
7. Tap “No”.
8. Attempt to tap each segment, observe the [ngSwitch] does not operate.

    return new Promise((resolve, reject) => {
      let alert = this.alertCtrl.create({
        title: 'Log out',
        subTitle: 'Are you sure you want to log out?',
        buttons: [
          {
            text: 'No',
            role: 'cancel',
            handler: () => {
              reject();
            }
          },
          {
            text: 'Yes',
            handler: () => {
              alert.dismiss().then(() => {
                resolve();
              });
            }
          }
        ]
      });

      alert.present();
    });
