FAB not moving down on Snackbar dismiss

Question

On my phone and that of a friend, the FAB in the default Android Studio Activity does not move down after the Snackbar dismisses.

On the emulator and a few other friends' phones, it does animate down.

The first friend and I have changed animation scale to 0.5, but setting it to 1.0 and rebooting hasn't fixed the issue.

This should have been fixed in Design Support Library 23.2.0, and I am using 23.3.0, as the example comes with that set.

Edit: The layout and code for completion purposes:

content_main.xml

<?xml version="1.0" encoding="utf-8"?>
