Runtime error during call ProgressBar.setFill() with sprite argument.

[mdgfox]

I guess the next fragment is wrong(with "if (!this.fill)") is wrong and it should be the same as in main branch.

if (this.options?.nineSlicePlane)
{
        if (typeof fill === 'string')
        {
            this.fill = new PixiNineSlicePlane(Texture.from(fill), ...this.options.nineSlicePlane.fill);
        }
        else if (fill instanceof Texture)
        {
            this.fill = new PixiNineSlicePlane(fill, ...this.options.nineSlicePlane.fill);
        }
        else
        {
            console.warn('NineSlicePlane can not be used with views set as Container.');
        }
}

if (!this.fill)
{
      this.fill = getView(fill) as Sprite | Graphics;
 }

Expected Behavior

No runtime errors.

Current Behavior

Runtime error with next stack-trace
"Cannot set properties of null (setting '_parentID')
at _Container2.addChildAt (...)
at ProgressBar.setFill (...)"

Possible Solution

I guess there is the correct way of implementation in current main branch.

Steps to Reproduce

1. Create Progress bar
2. Call progressBar.setFill(new Sprite("some_sprite");
