How to reproduce the issue:
On initial click on a story, everything is good. Switch to a different story- good. Switch back to the first story- boom.
This appears to be a race condition that is adjacent to what we saw in #2164 and @danilobuerger fixed in #2165. I have spotted a potential root cause - working on it and PR now.
