As weird as this issue may seem, there's a very good reason as to why this is happening.
While I was investigating the code behind this, I learned that the mist wolf checks the block brightness at its location. It only inflicts blindness if it's in a dark area. Since the mist wolf is in a block, it thinks the brightness is 0, and causes blindness, while being out in the open causes it to fail since its bright. Spawning the wolf in a cave, or the dark forest where it's supposed to live will give you the effect when it attacks.
Closing this as it works as intended, this is just a special case
