Strange border on IonItem

There’s a strange border that appears on an IonItem when long-pressing. I’m using Chromium Edge to simulate an iOS device.

<IonItem button={true} detail lines="none">
   <IonText color="primary">
     <h6>Next 7 days</h6>
    </IonText>
</IonItem>

Have you tried it on iOS? Could be a discrepancy in Chromium.
