Statistics bug: "Future Due" excludes buried cards

(Anki 2.1.61)
I think the following behavior occurs because I often bury cards.

Last night, “Future Due” showed 102 cards would be due “tomorrow” (which is now today) and no backlog, out of 3405 reviews total.

But this morning, “Future Due” shows 129 cards due today, with a backlog of 70, out of 3994 reviews total.

Yes, I can confirm Anki currently does not support including buried cards in that graph.
