`@param with name "foo", which was not used` When Parameter Name Matches Excluded Property Name From Parent Class

The signature Foo.constructor has an @param with name "bar", which was not used

Expected Behavior

The behavior from TypeDoc versions 0.26.1 and below is expected. The documentation should not exclude documented parameters, nor should it warn about unrelated properties.

Actual Behavior

When a parent class (A in this example) has an excluded property (a in this example) with a name that matches the name of a child class' (B in this example) constructor parameter, a warning is given and the parameter is excluded from the documentation.

Steps to reproduce the bug

1. Install TypeDoc version 2.6.2, 2.6.3, or 2.6.4.

2. Enable excludeInternal in your TypeDoc configuration.

3. Use a file with the following contents as an entrypoint.

   export abstract class A {
     protected constructor(a: number) {
       this.a = a;
     }
   
     /** @internal */
     public readonly a: number;
   }
   
   export class B extends A {
     /** @param a */
     public constructor(a: number) {
       super(a);
     }
   }

4. Execute typedoc.

The following warning messages will be displayed:

[warning] The signature B.constructor has an @param with name "a", which was not used
[info] Documentation generated at ./docs
[warning] Found 0 errors and 1 warnings

Additionally, the generated documentation will exclude a from the constructor of B:

Environment

• TypeDoc version: 2.6.4
• TypeScript version: 5.4.5
• Node.js version: 22.3.0
