Website Translation from German to English fails on Robo

[AMindToThink]

I would like to do the "Robo" section, which is in German.
I tried Google Chrome's Translate feature as well as Google Translate and Yandex. They all say they cannot translate it.

My expected output is to see the German text in English but the rest of the webpage the same.

Translating the English Natural Number Game into Spanish or German with Google Chrome's Translate feature works properly. Google Translate and Yandex fail on the Natural Number Game.

In Firefox, automatic translation of Robo to English works for me:

Of course, I cannot guarantee for the quality of the translation.

Please bear in mind that the game is heavily under development. Only around half of the visible planets are in a polished state. Feedback is highly welcome!

If you have any technical insight why it doesn't work, please don't hesitate to tell us here what needs to be changed.

However, note that I don't think I will investigate this myself, nor do I currently have any intention that automatic browser translation should become an officially supported feature. :)
