bug: modal from ModalController opening twice

[aleksander351]

Prerequisites

• [X] I have read the Contributing Guidelines.
• [X] I agree to follow the Code of Conduct.
• [X] I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v7.x

Current Behavior

When I open a modal with the click of a button, the modal shows up twice. As you can see from the image, the <ion-app> element appears only once in the application. Some post suggested the problem is because there are multiple instances of <ion-app> on the page.

Expected Behavior

Modal should show only one instance.

Steps to Reproduce

The code of the controler

async openPreviewModal(): Promise<void> {
    const previewModal1 = await this.modalCtrl.create({
      component: PreviewModalComponent,
      cssClass: "preview-modal",
    });

    previewModal1.present();
  }

turned out it was a problem with swiper.js

adding (click)="$event.preventDefault(); solved it for me.
