For some reason, "right-middle" and "left-middle" attributes do not render consistently on page 123r. I changed two margin notes from "right-middle" it to "right-top." This should hopefully fix the bug.
@Pantagrueliste This is a known actual bug documented in Nick's repo that he will be working on. This is not the only folio for which this is a problem. Thus far, it has made no difference whether you give the margin blocks in question "right-top," "right-middle," or "right-bottom" designations—hence, it is a legit bug. So, can you please put the position attributes back to "right-middle," since that's the position marker it should have and that should work once Nick resolves the bug.
See outstanding rendering problems not having to do with source data or values are: Extra wide: cu-mkp/making-knowing-edition#70 Right margins: cu-mkp/making-knowing-edition#173
Commit reverted. Thanks for the clarification.
