Issue with the pixi inspector: Uncaught DOMException: Failed to execute 'postMessage' on 'Window': scrollbarMove(e)

[IJsLauw]

Whenever I try to inspect a pixi instance with a scrollbox on it I get this error:

Uncaught DOMException: Failed to execute 'postMessage' on 'Window': scrollbarMove(e) { if (this.pointerDown) { if (this.pointerDown.type === 'horizontal') { ...... } could not be cloned.

I am almost sure that is worked at some point, but in the state it is in now I can only get rid of the error by removing the scrollbox. Has anyone experienced this before and is there a workaround?
