Where did you find code that uses org-element-property on a link like this?
This won’t work with org-link-set-parameters because the face function does
not get an org-element, it gets only the path part of it.

I don’t think you can use edebug in font lock functions. I always use the
old fashioned (message “%s” thing-i-want-to-see) approach.

Maybe there is some fancy way to do it, e.g. font-lock-studio, but I don’t
do it often enough to be fluent in fancy things!
