I see they set both visibility:hidden and visibility:visible but Firefox let's visible override hidden here.

It's not too uncommon for websites to just end up as blank slates with noscript, I just never expect it to be because they literally told the browser to hide it and somehow scripts tell the browser to nevermind that and show it.
