[wcs-select/form-field]: indication required manquante au lecteur d'écran

Description

<wcs-form-field>
<wcs-select placeholder="Select a country (select custom)" required="" class="hydrated" overlaydirection="bottom" tabindex="0" role="combobox" aria-haspopup="listbox" aria-owns="OPTIONS-0.gjbvav3bc7" aria-controls="OPTIONS-0.gjbvav3bc7" aria-expanded="false" aria-multiselectable="false" aria-label="What country music are you coming from, dude? (select custom)" size="m" aria-description="You can identify the person by the country music he lives in" aria-invalid="false">
</wcs-form-field>

On voit qu'il n'y a pas de aria-required alors qu'on passe la prop required
