Rerendering List Replaces First ListItem #307

Open cwarden opened 4 months ago

cwarden commented 4 months ago

When a List is rerendered, the first listitem is replaced. If it has focus, it loses focus. The other listitems don't have this problem.

Here's an example using the todomvc application.
