bug: Angular: Modal does not open when using ModalController and the component declares an InputSignal with the root

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

1. Go to https://stackblitz.com/edit/kodxyzx4?file=src%2Fmain.ts
2. Click on open modal. (This opens with an empty nav)
3. Refresh
4. Click on 'Open nav with if' (This opens with a filled nav)

Hey, thanks for the report! This had been fixed in v9 but has no reason not to be fixed in v8. The fix has been merged and will most likely be deployed Wednesday with our weekly update.

The fix for this is out now in 8.8.12!
