Javadoc overriding methods not inheriting @param descriptions

EDIT: This issue was originally about the {@inheritDoc} tag, but I realized it's actually caused by something else after some more experimentation.

When method Javadocs are inherited through {@inheritDoc}, the parameter descriptions are not shown in the hover popups.

When hovering over methods that override a parent method, the descriptions for @param tags in the parent's Javadoc are not inherited, which does not match the Javadoc tool's HTML output.

Environment

• Operating System: Ubuntu 18.04/20.04
• JDK version: 11.0.3
• Visual Studio Code version: 1.36.0-insider/1.56.0-insider
• Java extension version: 0.46.0/0.77.0

Steps To Reproduce

1. Open a new folder
2. Create two Java files:

public class Foo {
    /**
     * Foo.foo
     * 
     * @param i an int
     */
    public int foo(int i) {
        return i;
    }
}

public class Bar extends Foo {
    @Override
    public int foo(int i) {
        return i;
    }
}

3. Hover over the foo method name in Bar to see the Javadoc.

Current Result

When hovering above Bar.foo(int), in the Javadoc popup, the description for the parameter i is empty:

Expected Result

The description for i should be the same as in Foo.foo(int), which is what the Javadoc tool does:

According to the documentation of the Javadoc tool, the missing @param tags should have been inherited from the overridden method. This does work for @return and @throws tags, but not for @param tags.

Commencez par reproduire le comportement du survol avec les fichiers Java Foo et Bar de l’issue, puis comparez la Javadoc de la méthode redéfinie avec la sortie HTML de l’outil Javadoc. L’issue est terminée lorsque la description @param héritée pour i apparaît dans la fenêtre contextuelle du survol, conformément à la méthode parente et au comportement documenté de Javadoc.
