Of course -- a root is needed only by native code that wants a pointer 
or equivalent (jsval) to be a strong link that the GC starts marking the 
live-GC-thing graph from.  A property is by definition a strong link in 
the live GC-thing graph, so long as the object containing the property 
is itself in the graph reachable from the root set.
