Using pixi v8.3.4 and ui v2.1.5, when trying to use a nineslicesprite bg for an Input

[CyberDex]

Using pixi v8.3.4 and ui v2.1.5, when trying to use a nineslicesprite bg for an Input
, it fails with a console warning: NineSliceSprite can not be used with views set as Container.

const input = new Input({
  bg: Sprite.from(texture),
  nineSliceSprite: [7,7,6,6],
});```

In that case, It seems that latest the version prefers bg to be an actual string.
This is the code that handles this:

        if (this.options?.nineSliceSprite)
        {
            if (typeof bg === 'string')
            {
                this._bg = new NineSliceSprite({
                    texture: Texture.from(bg),
                    leftWidth: this.options.nineSliceSprite[0],
                    topHeight: this.options.nineSliceSprite[1],
                    rightWidth: this.options.nineSliceSprite[2],
                    bottomHeight: this.options.nineSliceSprite[3],
                });
            }
            else
            {
                console.warn('NineSliceSprite can not be used with views set as Container.');
            }
        }
