in this FAQ Thread it’s suggested to “Set a language preference cookie” by clicking “Yes” in the little dialog after changing the language on the MDN website. In macOS Safari (12.1.1) this function is broken.
If I click on “Yes”, this error occurs on the JS Console :
TypeError: undefined is not an object (evaluating 'mdn.utils.getCookie')
Therefore the language setting is not permanent for Safari Users. The site also ignores the setting in my Mozilla profile with which I’m logged in by the way.
Is there any official bug tracker where I can report this issue?
