    [WIP] Implementing lazy load feature for review request

    Review Request #11433 — Created Feb. 6, 2021 and updated

    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).

    I don't think these are changes we want to make, especially in the base class.
