Current Behavior

When opening a modal from a popover click event, if that modal has form fields, the first one is given immediate focus, then immediately blurred, causing a flashing effect.

Expected Behavior

The input field in a modal opened by a popover does not receive focus then immediately blur.

Steps to Reproduce

Create an inline popover that has a child with a click event that opens a modal that contains an input field.

Page with popover

<template>
  <ion-page>
    <ion-content :fullscreen="true" color="light">
      <ion-button @click="setOpen(true, $event)" shape="round" fill="clear" color="dark" size="small">
        <ion-icon :icon="ellipsisVertical"></ion-icon>
      </ion-button>
      <ion-popover :is-open="isOpen" :event="locationEvent" :dismissOnSelect="true" @didDismiss="setOpen(false)">
        <ion-item class="context-item" lines="full" @click="openModal">Test</ion-item>
      </ion-popover>
    </ion-content>
  </ion-page>
</template>

<script lang="ts" setup>
import { ref } from 'vue'
import { IonButton, IonPopover, IonIcon, IonPage, IonContent, modalController, IonItem } from '@ionic/vue';
import { ellipsisVertical } from 'ionicons/icons';
import ModalVue from './Modal.vue';

const isOpen = ref(false);
const locationEvent = ref<Event>();

function setOpen(state: boolean, event?: Event) {
  locationEvent.value = event;
  isOpen.value = state;
}

const openModal = async () => {
  const modal = await modalController
    .create({
      component: ModalVue
    })
  modal.present();
  await modal.onDidDismiss();
}
</script>

Modal.vue

<template>
  <ion-item>
    <ion-label position="floating">Label</ion-label>
    <ion-input></ion-input>
  </ion-item>
</template>

<script lang="ts" setup>
import { IonItem, IonLabel, IonInput } from '@ionic/vue';
</script>

@raymer thanks for reporting this issue. I'm able to replicate against your reproduction.

It does look like our focus trapping behavior is setting focus on the first form control and then immediately changing focus to the root ion-modal node, which causes a visual defect.

We will track this as a bug and prioritize.
