- [X] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already report this problem, without success.

### Ionic Framework Version

v7.x

### Current Behavior

When rendering an `ion-input` with the `clear-input` option enabled, it will cause centered placeholder text to be shifted by the space that the clear button would render, when a value is set.

### Expected Behavior

The clear button should not take up available space until the control has a value. For example, the Reminders app from iOS:

|Without Value|With Value|
|---|---|
|Even spacing on each side (`115px`)|No longer centered to entire container|
|||

### Steps to Reproduce

1. Open the reproduction
2. Observe: The placeholder text is shifted when the `clear-input` is enabled, even if there is no value set.

### Code Reproduction URL

### Ionic Info

N/A

### Additional Information

The visually centered placeholder is present in iOS 16.4, but in the 16.5 beta there is different visual behavior in the reminders app. We are unsure if it is a bug or a change in design at this time.

Attaching video comparisons of difference in behavior we are currently seeing across iOS versions with the iOS Reminders app:

|iOS 16.4|iOS 16.5 beta|
|---|---|

Open the StackBlitz reproduction at index.html and run it with an ion-input using clear-input enabled. Compare the placeholder position with and without a value, and consider the issue done when the empty control keeps its placeholder centered while the clear button appears correctly for a populated control.
