Firefox-only: recursion error in compiling CDXlines #3344
Description
https://perma.cc/Z99B-6NRL doesn't play back in Firefox because the service worker runs aground when compiling its CDXlines.
This happens if you load the WARC directly in https://replayweb.page/ as well; it's not specific to our environment.
It's perfectly fine in Chrome, Edge, and Safari.
Could be interesting to try to identify what's up with the CDX in question; we could also report to Webrecorder.
