Hello,
Awesome project, I hope it is still alive :) !
This QR Code image cannot be read by jsQR, even with a high quality screenshoted image:

It is parsed by some other libs.
It should find the following data:

Found the same issue when using it from blazor via ReactorBlazorQRCodeScanner nuget. I use an even smaller QR code, but bigger than the standard single-alignment-node codes, and I cannot retrieve its content.
