Impossible to styled with props for nested component with applyTheme

[clementloridan]

Describe the bug

I want to do this:

`
import { SelectMenu as SelectMenuBumbag, applyTheme } from 'bumbag';

const SelectMenu = applyTheme(SelectMenuBumbag, {
styles: {
base: p => {
return {
width: p.autoWidth ? 'auto' : '100%',
};
},
},
Button: {
styles: {
base: p => {
return {
display: p.autoWidth ? 'inline-flex' : 'flex',
};
},
},
},
defaultProps: {},
});

export default SelectMenu;

`

But the styles of the SelectMenu Button was not apply.
