Tab content become empty when change tabs. Happens only on iOS 14.5 upwards

[smartsanja2013]

I am using ionic2-super-tabs v4.3.1. I have 3 tabs which is used inside a component (It is not for main navigation. Using as a segmented control). I have set a component as the Root.
For the first time page load, tab 0 is selected by default. Content of this tab is visible. When selecting the 2nd tab, the contents become empty. Also, when selecting the 1st tab again, it's content also become empty.
Issue is started to happen suddenly only on iOS v14.5 upwards. All other iOS versions and Android no issue.

Child page module

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { ChartPage2 } from './chart2';


@NgModule({
  declarations: [
    ChartPage2,
  ],
  providers: [],
  imports: [
    IonicPageModule.forChild(ChartPage2),
  ],
})
export class ChartPageModule {}

Child page

import {Component} from '@angular/core';
import {IonicPage} from 'ionic-angular';

@IonicPage()
@Component({
  selector: 'page-chart2',
  templateUrl: 'chart2.html',
})
export class ChartPage2 {

  constructor(){
    console.log('RootPage init');
  }

  public onEnter(): void {
    console.info('Workaround: Tab1Component -> onEnter. Loaded state:');
    this.initView();
  }

  private initView(): void {
    console.log("Root page InitView")
  }
}

Child page html

<ion-content>
  <div class="taptoretry">
    <div style="font-weight: bold; color:black; font-size:110%; display: inline;color :rgb(70, 69, 69);">There is content in the root component.
    </div>
  </div>
</ion-content>
