> prefetchOnElement takes a single StateAccessor corresponding to the root 
> trigger.  It uses that state accessor to perform prefetches for the 
> subtrigger state. However that will use the root trigger namespace for the 
> tags in the subtriggers.  This makes prefetching ineffective, introducing 
> possibly an additional round-trip once the data is actually read.
