bug: Ionic 8.6.0 and above issues with ion-label and ngx-translate

### Prerequisites

- [x] I have read the [Contributing Guidelines](https://github.com/ionic-team/ionic-framework/blob/main/docs/CONTRIBUTING.md#creating-an-issue).
- [x] I agree to follow the [Code of Conduct](https://ionicframework.com/code-of-conduct).
- [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

v8.x

### Current Behavior

Using ngx-translate (any version) and the [translate] directiive only with ion-label causes the label to duplicate many times. Changing to any other tag such as ion-text works fine.

Something changed with ionic 8.6.0 as with 8.5.9 there is no issue.

### Expected Behavior

Should show the label once.

### Steps to Reproduce

1. use a blank ionic project (ng-modules)
2. add ngx-translate
3. add to app.module.ts `TranslateModule.forRoot({
defaultLanguage: 'en'
})],`
4. add import of TranslateModule to home.module.ts
5. Add this line to home.page.html ``

This is result:

### Additional Information

_No response_

Start with the blank Ionic Angular reproduction, configuring TranslateModule in app.module.ts and home.module.ts and placing the translate directive in home.page.html. Compare behavior between Ionic 8.5.9 and 8.6.0 or later around ion-label; done means the translated label renders once rather than duplicating.
