View flashes with Fade.In before transition finishes

I'm on the 2.1.5-SNAPSHOT to try out the SharedElementsTransitions.

[This is the issue I'm having.](http://i.imgur.com/W4I0H3T.gifv)
In my app I have `LibraryController` which has a ViewPager. In this scenario a childcontroller, one of the tabs, is pushing a new controller to the router of the parent controller instead of the `LibraryController` router to not show the tabs using with this code:

private void onAlbumClick(Album album, int position) {
String titleSharedElementName = getResources().getString(R.string.transition_tag_title_indexed, position);
String imageSharedElementName = getResources().getString(R.string.transition_tag_image_indexed, position);

getParentController().getRouter()
.pushController(RouterTransaction
.with(new AlbumDetailController(album, position))
.pushChangeHandler(new ArcFadeMoveChangeHandler(titleSharedElementName, imageSharedElementName))
.popChangeHandler(new ArcFadeMoveChangeHandler(titleSharedElementName, imageSharedElementName)));

}

`ArcFadeMoveChangeHandler` is the exact same as used in the Demo to create a shared element transition but for some reason during the transition I can see the view fade in twice, almost like it flashes. The behavior occurs either with the `getParentController()` or not so maybe it's an issue with the transition starting within the `RouterPagerAdapter`?

Reproduce the flash using the SharedElementsTransitions setup and the provided LibraryController flow. Start by inspecting RouterPagerAdapter and ArcFadeMoveChangeHandler, then compare the behavior with the Demo's shared-element transition. Done means the view no longer visibly fades in twice during the transition.
