vue-client-only | Vue component to wrap non SSR friendly components | Server Side Rendering library

I am trying to render a Leaflet map using Vue2Leaflet in a jsfiddle so I can get help with a specific problem but I can't even get it to render properly in the trivial case. I have already looked up how to load libraries via CDN in jsfiddle and a far as I can tell, I am doing it right. There are also no errors in the console. But the map will not render.

This is the jsfiddle: https://jsfiddle.net/iboates/bywzgf1q/3/

Vue2Leaflet also requires the vue-client-only library. I have it working in my local codebase but maybe it has something to do with why it isn't working in jsfiddle. I am also loading this library via a CDN.

I've also looked at other jsfiddles using Vue with custom libraries loaded via CDN and I don't see what is being done differently.

Apparently StackOverflow requires that a jsfiddle link requires code in the post as well, which is a bit weird to me since the code is literally contained in a link which can also execute it, but here it goes:
