<Select.Root id={id}> and <Combobox.Root id={id}> both pass id down to the Trigger part (the visible <button> form element), so sibling <label> id references work like <select id={...}>

The problem is Select is not suppressing this warning like Combobox does by generating an internal id when a name is missing, which it should do:

id={id && hiddenInputName == null ? `${id}-hidden-input` : undefined}
