FrameTimingManager.GetLatestTimings adds background time to the next focused frame when the Player is unfocused
How to reproduce:
1. Open the attached “TestBackgroundFrameTiming.zip” project
2. Enable “Frame Timing Stats” (Edit → Project Settings → Player → Other Settings)
3. Build and Run the Player
4. Focus and unfocus the Player (switching tabs, turning the device display off and on)
5. Observe the Logcat Console
Actual result: The 4th frame after regaining focus shows a spike in time (relative to how much time was spent unfocused)
Expected result: Frame timing is consistent (on an Android device ~33ms)
