Description

Currently, <select multiple [formField]="..."> is not supported in signal forms.

This is documented here: https://angular.dev/essentials/signal-forms#select-dropdowns

I did not find any existing issue for this feature so I decided to open one myself to be sure it would stay on the radar (and this is the only point blocking me for going full signal-forms).
