Did Toyota just not care that her eyebrow was falling off?

In this Toyota commercial, a woman is singing a Christmas-themed song about cars. Near the end of the commercial you can see that her right eyebrow is falling off. Did Toyota not notice? Did it know and just not care? Or did it know and realize it would be a good way to get idiots to share it online?https://youtu.be/CFkHDHxC8Os
