Hasn't some version of that bug existed since we added jump points in 4.0?

Yes. Different source cause, though, I believe. Well, that's why, coupled with this effort of prioritizing these issues, there's also the robustness evaluation we're doing across the board, right? Because it's not just about getting the bugs fixed and then they break again. It's about trying to change the culture behind how we fix them, and what we check in the periphery of the fix, right? So make sure it's root cause analysis and that it's not just a patch on top of another one, right?
