| * A bug in angular animation's `state` when ViewContainers are moved using ViewContainerRef.move() |
| * causes the animation state of moved components to become `void` upon exit, and not update again |
| * upon reentry into the DOM. This can lead a to situation for the expansion panel where the state |
| * of the panel is `expanded` or `collapsed` but the animation state is `void`. |
| * |
| * To correctly handle animating to the next state, we animate between `void` and `collapsed` which |
| * are defined to have the same styles. Since angular animates from the current styles to the |
| * destination state's style definition, in situations where we are moving from `void`'s styles to |
| * `collapsed` this acts a noop since no style values change. |
| * |
| * In the case where angular's animation state is out of sync with the expansion panel's state, the |
| * expansion panel being `expanded` and angular animations being `void`, the animation from the |
| * `expanded`'s effective styles (though in a `void` animation state) to the collapsed state will |
