Details

JSRuntime::finishPersistentRoots() clears the contents of persistent roots on shutdown. But it doesn't clear PersistentRoot<Maybe<T>> roots. There's no equivalent of the line in JSRuntime::tracePersistentRoots() that handles ConcreteTraceable roots.
This is problematic because we don't know the type of the rooted thing at shutdown. We only have a trace function for it. It might be possible to use ClearEdgesTracer here, but we'd have to fix bug 1422513 first.
