bug: card modal doesn't add border radius until the modal is fully opened on iOS

[zacksmash]

Prerequisites

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

Ionic Framework Version

v7.x

Current Behavior

When using the "Card' modal style, the "body" behind the modal window doesn't get the radius edges applied until after the modal window has fully opened. This only happens if opening the modal from an IonList > IonItem with the button attribute.

Expected Behavior

The Card modal should have the radius edges, like normal

Steps to Reproduce

1. Create an IonList element, with an IonItem that has the button attribute. Then use that IonItem to open an IonModal, with a presentingElement for the Card effect.

<template>
  <ion-page ref="presentingElement">
    <ion-header :translucent="true">
      <ion-toolbar>
        <ion-title>Blank</ion-title>
      </ion-toolbar>
    </ion-header>

    <ion-content :fullscreen="true">
      <ion-header collapse="condense">
        <ion-toolbar>
          <ion-title size="large">Blank</ion-title>
        </ion-toolbar>
      </ion-header>

      <ion-list>
        <ion-item button @click="isOpen = true">
          <ion-label>List Item Label</ion-label>
        </ion-item>

        <ion-modal ref="modal" :is-open="isOpen" :presenting-element="$refs?.presentingElement?.$el">
          <ion-header>
            <ion-toolbar>
              <ion-title>Modal</ion-title>
              <ion-buttons slot="end">
                <ion-button @click="isOpen = false">Close</ion-button>
              </ion-buttons>
            </ion-toolbar>
          </ion-header>
          <ion-content class="ion-padding">
            Some Modal Content
          </ion-content>
        </ion-modal>
      </ion-list>
    </ion-content>
  </ion-page>
</template>

<script setup>
import { IonContent, IonHeader, IonPage, IonTitle, IonToolbar, IonList, IonItem, IonLabel, IonButtons, IonButton, IonModal } from '@ionic/vue';
import { ref } from 'vue';

const isOpen = ref(false);
</script>
