So I looked into the tests. Even in terms of manual testing, this would still require using a debugger and breakpoints to see if the issues is fixed. I'm not sure whether this could still be considered a manual test if it involves that kind of setup

With the reproduction instructions of the linked JBS issue, this should always be testable for someone looking to test whether this fix works. The code from the monkey tester system info window perfectly manages to reproduce it. I updated the reproduction instructions a bit to make it more clear when it happens
