This won't solve the original issue since it was using a DefineMap. Is that being handled somewhere else?

getSetReflections.setKeyValue(target, key, shapeReflections.serialize(newVal));
} else {
// set no matter what
getSetReflections.setKeyValue(target, key, newVal);
}
} else {
var curVal = getKeyValue.call(target, key);

// if either was primitive, no recursive update possible
if(newVal === curVal) {
// do nothing
