Yes, this seems to be a different bug then.
I experimented a bit more and the error only occurs when a mobile device is used and the mobile theme is active. Using a desktop browser and switching to the mobile skin (minerva provided by MobileFrontend) works fine and using a mobile device with desktop theme (strapping) works as well.
Also: the “Mobile view” link at the bottom of https://www.whonix.org/wiki/Main_Page brings you to the .onion site.
This bug also affects the code selection. Until we have a solution I could edit the styles so it looks like JS was disabled and not so broken.
We could use widget parameters for that (migth also be useful for translations):
