There are countless tropes just like this that you don't even notice in your own native media that outsiders would call out or complain about. But the native, target audience "expects" to see certain things in certain ways because it communicates certain information quickly and effectively.
While I think most depictions of foreigners in native JP media is pretty cringe, I also don't see a reason why they should change it because it's not "for" the benefit of a gaijin like me. I also understand that these depictions aren't generally made with ill intent or meaning to disparage non-Japanese.
