Children propType parsed not as expected about react-docgen-typescript HOT 1 CLOSED

It's really coming from typescript as it is exactly what you get inside Text component from intellisense for this.children.
The reason why you get this is the type definition for React.Component<> which includes the following

        // React.Props<T> is now deprecated, which means that the `children`
        // property is not available on `P` by default, even though you can
        // always pass children as variadic arguments to `createElement`.
        // In the future, if we can define its call signature conditionally
        // on the existence of `children` in `P`, then we should remove this.
        props: Readonly<{ children?: ReactNode }> & Readonly<P>;

If I read that comment correctly, maybe one day that will be fixed there and everything will be fine.

Unfortunately, I am not seeing any simple/easy trick how to "fix" that. I also think that it could bring more problems as well.

Maybe one solution that you could use is creating a simple wrapper around the parse method. In that wrapper just iterate over all components and their properties and for children with specific type return string instead.
