bug: ion-radio does not keep checked-state after updating the underlaying object

Ionic Framework Version

v8.x

Current Behavior

Initially, the ion-radio-button is checked correctly. But after updating the objects that contain the data that is used to display the ion-radion-buttons, the checked-state gets lost, even though the value property stays the same. Seems that this bug appears on Angular standalone projects.

Perhaps this error could be related to the following issue: #29414
It could also be that this error can be found in other components, such as ion-accordion.

Expected Behavior

The active ion-radio-button should be highlighted when it's value matches the value of it's containing ion-radio-group - as was the case before standalone components.

Steps to Reproduce

1. Go to https://stackblitz.com/edit/angular-vquurr-ec7ark?file=src%2Fapp%2Fexample.component.html
2. Click the "Update Data" Button

Same for ion-accordion: https://stackblitz.com/edit/angular-vquurr-6urqjk?file=src%2Fapp%2Fexample.component.html
And maybe ion-checkbox, ion-toggle, ion-menu are also affected. Can someone from the Ionic Team whith deeper understanding in code architecture investigate if this bug applies to more components?
