The value is not handled by the Dropdown.value component?

[Powerplex]

Actually no :) We read the Radix doc too fast last time. Dropdown.Value is just for the display of the current selected value inside the trigger, but it does not manage it. Radix doc about Dropdown.Value: "The part that reflects the selected value. By default the selected item's text will be rendered."

All the main props are on the root element: https://www.radix-ui.com/primitives/docs/components/select#root

And this is also how we did for other components until now:
