/**
* Animations used by the Material expansion panel.
*
* 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
* occur as expected.
*
* Angular Bug: https://github.com/angular/angular/issues/18847
