How can I fix broken image links in my pug included markdown files?

Question

i just need to rebase the incoming links in the markdown, so that they're relative to the pug document

structure

index.pug
articles/
  my-article.md
  my-image.jpg

pug

.article-body
  include:markdown-it articles/my-article.md

markdown

# my cool article

![my cool image](my-image.jpg)

i'd really rather not change my markdown link to articles/my-image.jpg, because that would break the markdown preview for editing, which would be an awful developer experience
