I've been busily converting my Wagtail site from wagtail-fontawesome to wagtail-font-awesome-svg, to make it work with Wagtail 2.15, but I've just run into an issue I'm not sure how to resolve. Our existing site uses the Solid and Regular versions of the "user" icon, and I don't see any obvious way to register and use both of them.
The system appears to use the final part of the .svg file's name as the "name" for the icon, and both of these "user" icons are named user.svg. They're just in different folders, which doesn't seem to be addressable in the icon_name or icon settings for menus/blocks.
What can I do?
