For bugs, it comes down to how critical it is, if it's in the critical path to a function, and how common it is that someone would run into it trying to execute a function. For instance triage issues tend to be prioritized higher than issues in the webhook setup flows, since triage is a much more common action than webhook setup. This is also weighed with the time necessary to fix an issue, the team available to fix it, and the budget available for it.
