Unresponsive page and 100% of 1 CPU usage on some CI job page
After opening https://gitlab.com/coq/coq/-/jobs/234817191 in firefox 67.0.3 (debian), eg
firefox -no-remote -profile $(mktemp -d) -new-instance 'https://gitlab.com/coq/coq/-/jobs/234817191'
,
approximately once the log starts showing (saying "showing last of 499.99 kib" etc) clicking links in the page stops working and the CPU goes to 100% (1 core only)
I didn't leave it for more than a couple minutes so maybe it stops at some point.
