I had a very vim-mindset when writing the initial report and didn't
even consider that it could be an image rather than a character
in a custom font. But yes, I guess I do mean the bitmaps. But setting
`(set-face-attribute 'fringe nil :font "Cascadia Code" :height 220)`
will scale it correctly, so it can scale it if set explicitly, it just won't
do it automatically.
