trackedIssues
Every issue the current profile has in the download manager — queued, downloading, paused, failed or downloaded alike — in the order they were added, oldest first.
This is what a "my downloads" list is built from: pass each IssueId to issue to observe and control it. An issue drops out of the list when its download is cancelled.
