Hey,
I see in you github report, you have mentioned browser and OS as any. Its not where the issue is happening, its what you used to test your bug.
Also when you say, you can download all the files, you can download those anyways, this is a opensource project, you can look at the code and make whatever change you want. Question is can you deploy it to thr server without their permission?
