Steps to reproduce:

2. Add a select component with a few options in the middle of the page
3. Scroll through the page while the select is open

### Expected Behavior

Select menu height should increase when scrolled back into view

### Actual Behavior

Select menu height doesn't increase and stays small.


### Environment

- Angular: 19.2.7,
- CDK/Material: 19.2.10
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Windows

Inizia con la riproduzione StackBlitz collegata e segui il componente Select mentre scorri la pagina con il menu aperto. Confronta l'altezza del menu quando esce dal viewport e vi rientra; il lavoro è completato quando l'altezza si espande nuovamente dopo essere tornato a scorrere fino a renderlo visibile, come descritto nel comportamento previsto.
