Does bleeding gums invalidate wudu?

According to the Hanafi school, blood that flows from a wound on the body and exits the wound invalidates wudu. As for blood from the gums, if the amount of blood mixed with saliva is equal to or greater than the saliva, it invalidates wudu. (Mevsılî, el-İhtiyâr, 1/10)

According to the Shafi'i school, wudu is only invalidated by things that exit from the front or back private parts. Fluids coming from other parts of the body do not invalidate wudu. Therefore, according to the Shafi'i school, bleeding from the gums does not invalidate wudu. (Mâverdî, el-Hâvî, 1/199-200)
