v6 TS Missing static properties when component is wrapped by styled-component

[oskarwrobel]

TS does not see static properties when component is wrapped by styled-component.

Reproduction

function MyComponent({ className }: { className?: string }) {
  return <div>My component</div>
}
MyComponent.SomeStaticData = "Foo bar";

const StyledMyComponent = styled(MyComponent)`
  color: blue;
`;

return (
  <>{StyledMyComponent.SomeStaticData}</>
);

Property 'SomeStaticData' does not exist on type 'IStyledComponent<"web", typeof MyComponent, { className?: string | undefined; } & object> & object'.ts(2339)

Example: https://codesandbox.io/s/keen-euler-gxn4zj?file=/src/App.tsx
(CodeSandbox supports styled-components 6.0.0-beta.14 however it works exactly the same for 6.0.5)

Steps to reproduce

Wrap a component that contains static properties.

Expected Behavior

Static properties should remain accessible.

Actual Behavior

TS does not see static properties.
