Properties by an implemented interface's parent are included in the generated class type

Description

Please forgive the awful title.

Let's take example of Gtk.MediaStream: It implements Gdk.Paintable, and Gdk.Paintable requires GObject.Object.

However, in the types of Gtk.MediaStream, types for GObject.Object are included.

Current vs Expected Behavior

Current:

abstract class MediaStream extends GObject.Object implements Gdk.Paintable {
	// these should NOT be here
            bind_property(
                source_property: string,
                target: GObject.Object,
                target_property: string,
                flags: GObject.BindingFlags | null,
            ): GObject.Binding;
            bind_property_full(
                source_property: string,
                target: GObject.Object,
                target_property: string,
                flags: GObject.BindingFlags | null,
                transform_to?: GObject.BindingTransformFunc | null,
                transform_from?: GObject.BindingTransformFunc | null,
                notify?: GLib.DestroyNotify | null,
            ): GObject.Binding;
            // Conflicted with GObject.Object.bind_property_full
            bind_property_full(...args: never[]): any;

Expected:

All those types not to be included, because they are from GObject.Object

Also, note how there are 2 different declarations for bind_property_full, and the second one breaks things.

see above
