Generally when a ticket gets closed that means it has been escalated to the appropriate division. Any forthcoming fix will be in a future patch - as they can't generally add in new code without a patch.
And sometimes it can take quite a while to find the reason for the bug. Reporting it just makes them aware of it. That's why they as you to give as much detail as possible about what you were doing so they can replicate it to find the culprit. So it's very important for them to know the exact steps you took when the bug occurred.
