bug: Angular: Modal does not open when using ModalController and the component declares an InputSignal with the root #31220
Description
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
When using ionic/angular: ^8.8. When we use ModalController with a dynamic root input that is given to the nav. It will open an empty nav.
Expected Behavior
When ModalController opens a component that contains an ion-nav, and that nav's root is set dynamically via an InputSignal, the nav should render the root component.
Steps to Reproduce
- Go to https://stackblitz.com/edit/kodxyzx4?file=src%2Fmain.ts
- Click on open modal. (This opens with an empty nav)
- Refresh
- Click on 'Open nav with if' (This opens with a filled nav)
