Ionic Framework Version

v7.x

Current Behavior

A php file with a simple form containing an ion-select (3 options) and an ion-input.

The posted page has only input_text (the ion-input) in the request. Nothing about select_abc (the ion-select).

Expected Behavior

The posted page should show the posted data in the ion-card at the bottom the ion fields should have the posted data as value set.

Steps to Reproduce

1. Select an option in the ion-select field
2. Input some data in the ion-input field
3. Submit form
