Scanning Qr Code from Image 2D does not work in Demo

[MoritzWill]

The demo for scanning QR Codes from images does not work in the official demo:
https://zxing-js.github.io/library/examples/qr-image/

If you click on decode, the result is just N, eventhough it should scan the shown QR Code and show its content.

Thank you!

I have the same problem. The strange thing is that I can get the correct barcode by clicking decode button again.
