Since v0.20: Type arguments are not used when extending a template class implementation

Expected Behavior

When a class is extending a template class implementation (using type arguments) the type arguments should be used as types in the sub class.

Actual Behavior

The sub class is rendered by TypeDoc with the type parameters instead of the type arguments. This was working fine back in version 0.19.2.

Steps to reproduce the bug

Example module:

export class TemplateTester<A, B = number> {
    public aaa: A;
    public bbb: B;
    public aOrb: A | B;
    public unionAB: string | A | Readonly<A | B>

    public BaseMethod(param1: A, param2: B): void {}
    public StaticMethodWithTypeParameters<A, B>(p1: A, p2: B): void {}
}

export class TemplateTesterSubClass2 extends TemplateTester<number> {
}

Environment

• Typedoc version: 0.20.5
• TypeScript version: 4.1.3
• Node.js version: 12.13.0
• OS: Windows 10

Shoot... I thought I'd fixed this, I guess the fix only worked for methods. Fixed in 0.20.6, publishing shortly

Thanks for the quick fix. I'll check it out soon.

Looks better now. 👍 I still found a difference and created a new issue #1441 for it.
