Prop types are lost when using memo

[Konstantin Azizov]

I've noticed that with move to typescript while losing memo from react-tracked props types defined as generics to FC or VFC are not being passed through unless they are specified in callback arguments itself. I've tried fixing it myself but wasn't able to unfortunately, hence made this issue.

// Works
const MyComponent = memo(({ foo }: { foo: string }) => {})

// Doesn't, typeof foo is 'any'
const MyComponent: FC<{ foo: string }> = memo(({ foo }) => {})

Here is another example in sandbox:
