addProperty("ADBE Text Tracking Amount") returned the first property added to the animator, which is
the Tracking Type companion, so the script changed the wrong value. The engine now reports the
requested property's position in the Properties group, and the script returns that property. An
animator's Properties group also finds its properties by their After Effects names, such as
ADBE Text Tracking Amount, which the name table already had in the other direction. A regression
test checks the property returned, its value, and the lookup by name.
Not covered: the Advanced and Wiggly selector children and the Expression amount, which still keep
their own names.
