Bindings/Refs Tutorial Section broken

[Crisfole]

Describe the bug

I was running through the tutorial when I hit the bindings/refs segment:

https://www.solidjs.com/tutorial/bindings_refs?solved

Nothing happened. I can see the onMount and loop functions being called (logs demonstrated that), but the putImageData is a no-op (which definitely doesn't make sense).

I tried this in both Chromium Edge and Firefox.

I'm on a Windows machine.

Expected behavior

I expected to see something (anything really) rendered to the canvas. I haven't read the code carefully enough to know what I should be seeing.
