bug: (ion-slides) getActiveIndex()

[sercatven]

Bug Report

Ionic version: [x] 5.x [x] Angular 9.x.x

Current behavior: When you open a new page with slides you only get the index of slide in the first opening. If you go back and access again, it does not recover the index.

In Angular 8 works fine.

Steps to reproduce: Home --> Slides --> getActiveIndex() OK --> Home --> Slides --> getActiveIndex() not work

    });
  }
