    // TODO future work: if the selection language is lower in the search results such that its
    // language card isn't initially visible, we should automatically scroll to it

I've already done this but forgot to delete the comment

                  <LazyLoad
                    offset={initialScrollingNeeded ? 1000000 : 500} // Normally, load a 500px buffer under the visible area so we don't have to get the calculation perfect. But if initial scrolling is needed, load everything so we can scroll the appropriate amount

Looks like this was actually unnecessary - when appropriate we scroll to the parent div, and then LazyLoad detects what is in the viewport and renders that, so no need to load all the cards even for initial scrolling
