I’ve played around with various things in the description field, and it is not working as you say.
Here is what I settled on in the edit window:
1. [CORE-1278: Large fluctuations of PID output after load removed](https://geo-jira.atlassian.net/browse/CORE-1278)
Here is a screenshot of the online version, where you can see that both last 2 lines are clickable (well, they are, but windoze screenshot is lame, so take my word for it):
Here is a screenshot of the PDF version of same, where only the last line, literally a URL, is clickable. The line above it is not. (Again, take my word for it.) (This is in the Chrome browser on windoze.)
TestRail version 22.214.171.12465
(BTW, when I click “check for update”, it reports:
You are already using the latest TestRail version (126.96.36.19963) and there is no need to upgrade your installation.
Which doesn’t match!)
