    textview: Use the adjustment target value to figure out if keynav failed
    
    When moving the cursor, compare current adjustment value with the post-animation
    target value, in order to avoid false "keynav failed" positives as the animation
    hasn't started yet, so dx/dy are still 0 at that time.
