[EinfachHans]

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

Maybe relative to #29782 (?) which sounds similar but for react

I mentioned that my IDEA (IntelliJ) doesn't know the type of inputs of core components correctly. But it can resolve them for components that are excluded in the proxy generation and manually created in the angular project like for example IonBackButton.

For example this is the view when i hover over the text input of ion-back-button

and this when i hover over the value property of ion-accordion:

Expected Behavior

All types should be resolved correctly

Steps to Reproduce

Open an example app in the latest IntelliJ version
