I can confirm something strange and unexpected is happening, arrays of arrays are stacking their bindings together.
Click 3 or more checkboxes from different groups and check how the pool is getting filled all mixed between then.

Here is a more verbose example which is also using keys but still suffer from the same problem.

I have also created the lists manually just to make sure that it wasn't the {#each} loop causing the issue and the problem seem to persists.

Noticed too...
Somehow fixes the problem, if you move the inner _each_ block to a separate component.

Same as earlier.

'Remaning' not working as expected, it should count only not done

$: remaining = todos.filter(t => !t.done).length;

It does if you complete the tutorial with the bind: statements as directed.

Using bind:group inside of an {#each} should work now in 3.23.2 with the addition of #4868.
