Why Are Asian Men Stereotyped As Model Minorities, Yet Also Stereotyped As Short?

Remember how short men are stereotyped as being more angry? Short man syndrome, etc. Yet Asian men are stereotyped as more passive and rule-abiding, while also being stereotyped as short.

Shouldn't Asian men be angrier on average, or do racial stereotypes override height stereotypes? Almost like humanity's stereotypes barely make any sense.

I'm guessing when a short Asian is a good boy and doesn't rock the boat, he's stereotyped as a weak nerd, but the moment this society doesn't like him, they'll label him with Napoleon Complex.
