### Ionic Framework Version

v7.x

### Current Behavior

Content is pushed up on input focus on emulated chrome device

UPDATE: It happens on Android too, the extra space is also present when the Android native keyboard is pushed up

### Expected Behavior

Don't move

### Steps to Reproduce

If you go to the oficial documentation and turn on the device toolbar and focus an input, the content is pushed up

Without focus:

With focus:

### Code Reproduction URL

https://ionicframework.com/docs/api/input

### Ionic Info

Same as in the docs, I'm personally having the same issue on "@ionic/vue": "^7.6.3",

### Additional Information

I'm migrating from 6.x to 7.x, 6.x was fine.

Start with the reproduction at https://ionicframework.com/docs/api/input and inspect how scroll assist behaves when an input inside a playground iframe receives focus. Verify the result in the emulated Chrome device and on Android; done means focusing the input does not push the content up or leave extra space.
