duplicate note references

Created by: dananjohnson

Generating outputs from 'categories' or 'full' can lead to issues with duplicate note reference numbers when posts use footnotes. jekyll build throws warnings like this:

[pandoc warning] Duplicate note reference '1' "source" (line 1777, column 1)

A PDF outputted from this will show the wrong footnotes because it doesn't know which one to reference.

Is this an issue that the plugin could address? I'm thinking a unique ID would need to be created for each note reference. Or maybe Pandoc has a way to allow note numbers to reset at each post?
