Adding `.duration` to `data-show` expands hover area to include hidden sub-elements.

[BKFlister]

E.g a simple menu dropdown, show submenu on hover Menu. Adding .duration or .duration_500ms expands the hover-area for the menu to include the submenu. Making the submenu appear before hovering the menu-text Menu.

<div data-store="{'_open' : false}">
  <ul id="menu" data-on-mouseover="$_open=true" data-on-mouseleave="$_open=false" style="background-color: #666;">
    <li>Menu
      <ul id="submenu" data-show.duration_500ms="$_open" style="background-color: #eee;">
        <li>Home</li>
        <li>Contact</li>
        <li>About</li>
        <li>Login</li>
      </ul>
    </li>
  </ul>
</div>
