ReviewBoard currently renders all historic data for review request,

and the data ends up getting computed and loaded on the client, which 

makes things seem slow. In order to enhance performance, we would like 

to implement a lazy-load feature where collapsed review entries get sent 

to the client empty, and then fetch the content dynamically when and if 

the entry is expanded.

When we inspect elements on the browser, any entry boxes that is collapsed

will not render the body tag (the body tag will be empty).
