 * **Breaking:** Change the return type of `ComponentLifecycle.resolve()` from `ComponentLayout` to `InternalNode`.
 * New: Expose `visibleTop` and `visibleLeft` fields from the `VisibilityChangedEvent` to better understand which side of the component is hidden. Check out `VisibilityChangedEvent`'s javadoc for more info.
 * New: Expose mounted content from the `VisibleEvent`.
 * New: Lifecycle arguments are now optional in the spec. (e.g. `ComponentContext` is now optional in `@OnCreateInitialState`)
