bug: [vue] weird behaviour for ion-input focus within ion-modal #30013

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

v8.x

Current Behavior

I have created ion-modal and used the modelController to present the model (just copied the code from here,
the Modal.vue contains multiple ion-input and is triggered as

const modal = await modalController.create({
      component: Modal,
      initialBreakpoint: 0.5
    });

    modal.present();

when setting the initialBreakpoint the focus randomly moves the ion-inputs within the modal, when removing completely the initialBreakpoint it works fine.
see attached video

Expected Behavior

• moving between the ion-inputs should be smooth and focus should be set accordingly.

Steps to Reproduce

1. create a fresh new installation
2. copy the implementation from here
3. set initialBreakpoint to 0.5
