How to reproduce:
1. Open the attached project "InputLostTest.zip" and load Scene "SampleScene"
2. Open Unity Remote on a mobile device
3. In Project Settings -> Editor ensure the correct mobile device is selected
4. Enter Play Mode
5. In the Device Simulator (Window -> General -> Device Simulator) use the mouse to simulate a continuous touch
6. Without releasing your mouse, kill Unity Remote on the mobile device

Expected result: touch input does not get reset in Device Simulator
Actual result: touch input gets reset in Device Simulator

Reproducible with: 3.0.3-preview (2020.3.36f1), 2021.3.5f1, 2022.1.7f1, 2022.2.0a18, 2022.3.0a1

Notes:
- Ordinarily, any kind of touch on the Remote app resets the touch input from Device Simulator, however just putting the Remote app in the background does not reset it
- Reproducible both on iOS and Android
