Stackblitz demo in readme has a state bug on deleiton

[e111077]

Description

The state seems to get confused when you remove a todo

Repro

1. open demo in readme
2. check the first item
3. delete the first, selected, item by clicking the X on the right

Expected result

Nothing should be checked and there should be "2 items left"

Actual Result

The (previously) second item, which is now first is checked but not crossed out. Clicking on the check will turn it into 2 items left and again into 3 items left when there are only 2 items present.

Fixed in main!
