### Prerequisites

### Ionic Framework Version

v8.x

### Current Behavior

since angular 20.2.0 [released](https://github.com/angular/angular/releases/tag/20.2.0) recently and typescript v5.9 is being supported

I upgraded dependencies of my project and the message pop up when serving the project

```
X [ERROR] TS2320: Interface 'HTMLIonInputElement' cannot simultaneously extend types 'IonInput' and 'HTMLStencilElement'.
Named property 'autocorrect' of types 'IonInput' and 'HTMLStencilElement' are not identical. [plugin angular-compiler]

node_modules/@ionic/core/dist/types/components.d.ts:4326:14:

X [ERROR] TS2320: Interface 'HTMLIonSearchbarElement' cannot simultaneously extend types 'IonSearchbar' and 'HTMLStencilElement'.
Named property 'autocorrect' of types 'IonSearchbar' and 'HTMLStencilElement' are not identical. [plugin angular-compiler]

node_modules/@ionic/core/dist/types/components.d.ts:4888:14:

```

and my project went well with angular@v20.1.* and typescript@v5.8.*

### Expected Behavior

Success to build and serve

### Steps to Reproduce

1. update deps with angular@v20.2.0 and typescript@v5.9.2
2. try to serve with `npx ng serve`

Sorry for my poor English 😆

Start by reproducing the issue with Angular 20.2.0, TypeScript 5.9.2, and `npx ng serve`. Inspect the declarations around lines 4326 and 4888 in `node_modules/@ionic/core/dist/types/components.d.ts`, where the reported interface conflicts occur. Done means the project builds and serves without the TS2320 errors.
