using enzyme.mount().setProps with a react-redux Provider

I have a test which is setting props, to observe some changes in the component. The only complication is that I'm wrapping the rendered element in a <Provider> because there are some connected components further down the tree.

I'm rendering via

const el = () => <MyComponent prop1={ prop1 } />;
const wrapper = mount(<Provider store={store}>{ el() }</Provider>);

I'm then trying to observe some changes by using the following:

wrapper.setProps({ /* new props */ });
// expect()s etc.

The problem is that setProps() is not setting the props properly on the wrapped component. I assume that this is because <Provider> is not actually passing props through as it's not an HoC. Is there a better way to test this than just changing the locally scoped prop variables and re-rendering?
