Attempts to grab fonts from `${origin}/fonts`?

[josephrocca]

Using this example that's linked from the official blog post:

https://jsfiddle.net/gh/get/library/pure/pyodide/pyodide-blog/contents/demos/canvas-renderer-matplotlib/demo-1/

It tries and fails to get https://fiddle.jshell.net/fonts/DejaVuSans.ttf. I tried updating it to the lastest version by replacing the script tag with:

<script src="https://cdn.jsdelivr.net/pyodide/v0.25.1/full/pyodide.js"></script>

and swapping this:

matplotlib.use("module://matplotlib.backends.html5_canvas_backend")

for the newer:

matplotlib.use("module://matplotlib_pyodide.html5_canvas_backend")

But the same issue occurs. I'm guessing this is why the pan/zoom buttons of plots aren't the right size, and don't have any text in them, in the example linked above? (and also in the latest version of Pyodide)
