Ion-button inside ion-content causes memory leaks problem

Ionic Framework
1

I have a problem with Ionic 6 and ion-button. I use tabs and when I go to nested page and then click on back button page doesn’t clear memory and I have memory leaks. I happens if I pass ion-button into ng-content. Such error happens even I just put native html button

I have the very simple test-component

@Component({
  selector: 'app-test-cmp',
  templateUrl: '<ng-content></ng-content>',
})
export class TestCmp {}

Here is my nested page

@Component({
  selector: 'app-test-page',
  templateUrl: `
    <ion-header>
      <ion-toolbar>
        <ion-buttons slot="start">
          <ion-back-button></ion-back-button>
        </ion-buttons>
        <ion-title>Test</ion-title>
      </ion-toolbar>
    </ion-header>

    <ion-content>
      <app-test-cmp><ion-card>anything here</ion-card></app-test-cmp>
    <ion-content>`,
})
export class TestPage {}

This code works well. Here is my memory snapshot.

But if I put ion-button into app-test-cmp memory doesn’t clear.

@Component({
  selector: 'app-test-page',
  templateUrl: `
    <ion-header>
      <ion-toolbar>
        <ion-buttons slot="start">
          <ion-back-button></ion-back-button>
        </ion-buttons>
        <ion-title>Test</ion-title>
      </ion-toolbar>
    </ion-header>

    <ion-content>
      <app-test-cmp><ion-button>Ionic button</ion-button></app-test-cmp>
    <ion-content>`,
})
export class TestPage {}

Here is memory snapshot

It’s somehow connected to ion-content

This code works correctly but crash animation, etc.

@Component({
  selector: 'app-test-page',
  templateUrl: `
    <ion-header>
      <ion-toolbar>
        <ion-buttons slot="start">
          <ion-back-button></ion-back-button>
        </ion-buttons>
        <ion-title>Test</ion-title>
      </ion-toolbar>
    </ion-header>

    <app-test-cmp><ion-button>Ionic button</ion-button></app-test-cmp>

    <ion-content>
      ......
    <ion-content>`,
})
export class TestPage {}

Also it happens only if Chrome device emulator is enabled. If I’m testing as desktop browser it works well.
Here you can try it by yourself https://so-65135988-cswh8j.stackblitz.io/home (just go between details page and back several times and compare memory allocation when emulation enabled and disabled)
