Steps to reproduce:
1. Open the attached user's project "XR_PrefabRegression_2022.zip"
2. Open the prefab "HMD + Cam", and set the Position Input binding to "devicePosition [XR HMD]"
3. Exit editing the Prefab
4. Add "HMD + Cam.prefab" to SampleScene
5. Note the bindings were lost
6. Add "HMD + Cam (Input by Ref).prefab" to SampleScene
7. Note the references to the Input Actions asset persist

Expected results: Tracked Pose Driver (Input System) bindings on a prefab are not lost upon exiting editing the Prefab
Actual results: Tracked Pose Driver (Input System) bindings on a prefab become lost upon exiting editing the Prefab

Reproducible on: Input System 1.6.1 (2021.3.27f1, 2022.3.2f1, 2023.1.0f1, 2023.2.0a18)

Notes:
-This does not occur when using a reference to an Input Action Asset
