Mixed alignment (LTR and RTL) in language selection list?

Most answers to this question say that for instance Arabic text should be aligned right-to-left even if the rest of the page is in a left-to-right script such as English.

So, I was surprised to see that the language selector https://www.wikipedia.org shows all languages left-aligned (as seen on Ubuntu in English):

Both Wikipedia and Ubuntu are very international and are driven by very vocal communities so I don't think this choice is random.

My question: Is there something special about language selectors that makes it OK to have alignment ignore language direction?
