Steps to reproduce
1. Build and run the sample application (https://drive.google.com/file/d/0BzzMYfCAYzn4bHpqWGhKbV81cU0/view?usp=sharing )
2. A list of "Hello world!" with different colors appears.
3. Tapping the list uses the above mentioned design pattern to transition to a new fragment with the list where the order of items is inverted
Frequency
100% of the time
Expected output
A shared element transition animation should animate the tapped text item so that it translates to a new position in the new fragment.
Current output
The transition animation does not work with the Android API. However, it does work if V4 support library is used (the modified sample application with support library where the animation works can be downloaded here:https://drive.google.com/file/d/0B5UiL525C78tQ1BmSlRoMG4yeE0/view?usp=sharing ). The Android API classes are replaced by android.support.v4.app.Fragment, FragmentManager and FragmentActivity

Sorry I didn't realize the original sample app uses support library, so here is the correct version:
Steps to reproduce
1. Build and run the modified sample application which uses the original Android API (https://drive.google.com/open?id=0B5UiL525C78tV0E2ZlFHcFh3ZXM )

It uses android.support.v4.app.Fragment, FragmentManager and FragmentActivity instead of the standard Android API classes.

This issue is reproducible on Android N N2G47Z build on Nexus 5X.
However this issue is not reproducible on Android O Developer Preview 4(OPP4.170623.014) build.

Description
Transaction 1
- add B,
- hide B
Transition 2: when B is ready
- show B
- remove A
- add shared elements
- add to back stack
This all works well with AppCompatActivity and app.support.v4.Fragment. However, if I use the standard non-support Activity and Fragment, this does NOT work (I tested in Android 7.0 with nVidia SHIELD Tablet K1). This can be easily verified by running the following project, then changing support Activity and Fragment to the standard ones.
I assume the correct behavior is that the standard APIs which support the shared elements behave in the same way as the support library.
