I notice this problem too but I can't reproduce it in prototype & test environment. I will see what's special about this on enwiki

Okay, the problem got narrowed down a little bit. I was able to re-produce it in test but still unable to re-produce in my local dev. Looks like it's related to the number of characters inside template

{{more than of equals to 1000 chars}} -> no content
{{less than 1000 chars}} -> okay

This has been merged and it will be deployed with next deployment train if we don't schedule a deployment next week.

Marking as fixed since the article snippet now appears and the snippet content is relevant to the article itself
