Does Firefox 57 provide the keycode from keydown events?

Hello, I’m new to here.
It seems that Firefox 57 takes an apostrophe(`) and makes the keycode 0 (which is intended to be 96, I think).
So, I’ve got different results from Chrome. Is it normal, or only for me?

I’d recommend using the more modern key or code attributes to identify keys when possible. code is layout independent, so much better suited for keys like ` that some layouts do not even have. See https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code

Wow, I didn’t know it can be done in that way although that feature has low compatibility yet.
Thank you for the response.
