Hello! Just came across something I think might be a bug? The standard rule in McGill guide for referring to prior citations is ibid for the immediate proceeding footnote, and supra # to the original footnote citation. If the second footnote refers to the footnote right above it, it should just say Ibid.

The system seems seems to be set up like this, EXCEPT for "case" item types. I have included a screenshot below showing the issue:

In this example, 95 is a citation for a case. 96 refers back to the same case - it SHOULD say Ibid, because its referring to the reference immediately proceeding it.
In contrast, 97 is citing a book, and 98 is doing the right thing, with an Ibid.

Is this an issue with something I did, or potentially a bug in the style?

(side note: I really love the McGill Guide but know nothing about coding... If whoever is working on updating to the 10th edition wants any help regarding the style rules, since its not open access- I'm happy to help!)
