Since 0.26 Crossterm detects key release events for Windows which means that downstream has to explicitly ignore it if you only want one event to fire.

For example, this change to the lines in list.rs from line 188 should do it:

if let Event::Key(KeyEvent {
    code,
    kind: KeyEventKind::Press,
    ..
}) = event::read()?
{
    match code {
        KeyCode::Char('q') => return Ok(()),
        KeyCode::Left => app.items.unselect(),
        KeyCode::Down => app.items.next(),
        KeyCode::Up => app.items.previous(),
        _ => {}
    }
}

Should this be closed?

Possibly waiting for #778?
