v8.1.5

I created a custom session prop which was an object for e.g.

```auto
session.custom.thing =
{
 'param1': 1,
 'param2': 2
}

```

When I bound `session.custom.thing` to a View custom prop and then bound another custom prop to read one of the keys in `thing` e.g. `thing.param1`, the quality of that binding was `Bad_Stale`.
