I have last version of Firefox (56.0.2) and I have not problem:

But svg is probably not correct.

display is very bad for Microsoft Edge on my new windows 10 desktop  (pieces are shifted off the squares).   Works fine in google chrome and works fine on my phone!

Ah I updated to the latest version (56.0) and it works now! (I was using 52.0)

Thanks for fixing Microsoft Edge display!
