DisplayObject is displayed at the (0,0) position for 1 tick.

Hi.

I found an issue.

It's running example -> https://jsfiddle.net/vu7ryj9w/40/

I use pixijs and pixi-spine.

I tried to addChild displayObject in event listener of pixi-spine.

But, DisplayObject is displayed at the (0,0) position for 1 tick.

why
If displayObject is not child, updateTransform does not work.
DisplayObject was updated before pixi-spine be updated.
and I addChild displayObject in event listener of pixi-spine.
So, It's displayed at the (0,0) position before next tick.

solution
How about adding event-listener functions as tickers and executing them?

Any feedback would be appreciated. :)
