name: A closing fence one quote level deeper does not close a twice-quoted fence
why: Once a quoted fence is armed from the whole marker stack, what closes it has to be read the same way, and the depth is part of the reading: inside code every line is literal, so with two markers off this line is the text "> ```" and not a closer at all. An implementation that stripped the stack for the closing test but not the depth ends the fence here, and the comment below then arms a directive from inside code -- which is why the marker sits under it rather than beside it, since nothing else in the output would show the difference. The shallower direction is a rule of its own and carries cases of its own: a line quoted less deeply ends the container outright, the way the end of the quote does, so a fence line one level up closes nothing here and opens a fresh fence at its own level instead -- which is what CommonMark does with it, measured. Nothing after such a line is prose under either reading, which is why the deeper direction here can take the stricter answer at no cost.
