In loading the test page, a lot of the Wikipedia resources randomly show or don't show based on the Wikipedia API endpoint returning HTTP 503 (Service unavailable) randomly when a lot of requests are made at once.
There are a few different approaches that might help fix this:
set cache to true with requests (and make sure we're actually using cache?) so that we don't request all resources on every page load if they're already in the cache
make a per-service request buffer and request resources serially to avoid overload
only make requests on link mouseover instead of requesting all resources on page load (though this may result in unacceptable delay?)
make a request error handler that can retry requests after a (random, exponential backoff?) delay
