Thank you for reporting this bug!

Unfortunately, it seems to be user-dependent because it is working fine on my computer (macOs M1 with Chrome):

This is not entirely surprising because the simulation to generate the diagrams is run on client side in JS:

https://github.com/bbchallenge/bbchallenge/blob/ee3799e88b1d6a9a9cce9cd6f3de94bc977dcca8/src/lib/tm.ts#L241

It would be really cool to port this code in rust/WASM to allow for more efficiency and hopefully run more iterations on all devices.

Maybe @modderme123 would be interested!

It seems that it's a Firefox-specific issue (I'm using Firefox 100.0.2). Here is how it looks like:


ncaught (in promise) 
Exception { name: "NS_ERROR_FAILURE", message: "", result: 2147500037, filename: "https://bbchallenge.org/_app/chunks/tm-b1a12469.js", lineNumber: 7, columnNumber: 0, data: null, stack: "$@https://bbchallenge.org/_app/chunks/tm-b1a12469.js:7:2311\nx@https://bbchallenge.org/_app/pages/index.svelte-8d4a2129.js:11:18272\nts/<@https://bbchallenge.org/_app/pages/index.svelte-8d4a2129.js:11:19362\n" }
```

Ach! That's unfortunate!
