Type parameters of template classes should not be inherited

type-parameters, React.Component

Expected Behavior

When a class is extending a binding of the template class React.Component there should be no type parameters visible, because the extending class is not generic, but its base class is. Moreover the type parameters are: P, S and SS.

Example code:

class AlarmGrid extends React.Component<PropsFromRedux> {
  // *snip*
}

Actual Behavior

When a class is extending a binding of the template class React.Component the following type parameters are shown: S, SS and S. Which means that P is missing and S is displayed twice. But there should be none at all, as described above.

This was originally reported by by @Kerry-Cho on Gitter here.

Steps to reproduce the bug

1. Create a simple project
2. Do npm install react and npm install --save-dev @types/react
3. Create a class extending React.Component (see example code above)
4. Create the documentation using typedoc

Environment

• Typedoc version: 0.17.8
• TypeScript version: 3.9.6
• Node.js version: 12.13.0
• OS: Windows 10 (64-bit)

Turns out this can be fixed with the default values of type parameters solution too. The only difference here is that the React types are interfaces with type parameters.
