The solution script for the $effects tutorial found at 'apps/svelte.dev/content/tutorial/01-svelte/02-reactivity/05-effects/+assets/app-b/src/lib/App.svelte' has a minor bug: Pressing the slow down button too many times make the counter go up really fast from a certain threshold.
I'd guess it is a 32-bit integer overflow.
