Dynamically update body classes as param value changes

[Bill Dami]

I've noticed that if a bound property is passed to set-body-class, the body classes will not dynamically update to the new value, the component has to be destroyed and re-rendered/initialized. Is this something that could be added?

I have a use case where we want to use {{set-body-class}} in the application template, and is bound to the router's currentPath value (setting a dasherized class name on the body that reflects the currently viewed page route). However it only works for the initially rendered route.

Yes, this could be added, seems reasonable.
