I will look into that.
Update,
okay that is a bug in my Footnotes section clip. I checked the spec here:
https://www.w3.org/TR/dpub-aria-1.1/
And technically no "doc-footnotes" (note the plural) exists anymore. So a footnotes section may only have epub:type not an aria role.
The Insert Role handles that properly. The Insert Aria Clips did not. I will fix that.
