bug: Lifecycle hooks ionViewWillEnter, ionViewDidEnter aren't fired when navigating back to the page about ionic-framework

[thetaPC]

Thank you for submitting the issue!

This is working as intended. When you go from a tabs page to a non-tabs page (your child page), the entire tabs context is considered "leaving". However within the tabs context itself, Tab 1 is still active which is why the lifecycles are not firing on Tab 1 when going to a non-tabs page. You can test this by logging something in the ionViewWillEnter hook on the TabsComponent:

class TabsComponent {
  ionViewDidEnter() {
    console.log('view did enter 2');
  }

  ionViewWillEnter() {
    console.log('view will enter3');
  }
}

There's a workaround that might be of interest to you.
