NeuGFX State Restoration error

[TK-21st]

When using state restoration, I am getting this following error:

Uncaught DOMException: Failed to execute 'inverse' on 'SVGMatrix': The matrix is not invertible.
    at SvgPanZoom.handleMouseDown (webpack://NeuGFX/./node_modules/svg-pan-zoom/src/svg-pan-zoom.js?:444:97)
    at SVGSVGElement.mousedown (webpack://NeuGFX/./node_modules/svg-pan-zoom/src/svg-pan-zoom.js?:110:25)

The iframe shows up by there is no circuit diagram.
