Ah, I see what you are saying. Yes, they don't appear in the list before I type anything either, but my list had so many entries before the first on hold project that I had typed a character to get within sight of it, and doing so made them appear. To me, it looked like they were always there. Because sidebar order can be viewed as a form of prioritization, my on hold tasks (which are by definition not a current priority) tend to get shuffled down the sidebar.

Given that the on hold projects behave this way (and are shown in gray) I'm sure this is intentional behavior, not a bug. No need to wait, you should file your request now with Help->Send Feedback, and hope others do as well, but I wouldn't hold my breath while waiting for it to appear! There are many requests which have gotten plenty of votes ahead of it in the queue...
