[Mobile][InputSystem] IsPointerOverGameObject does not work on device when calling it directly as a Public method

Package: Input System

-

Steps to reproduce:
1. Open the user's attached project "InputSystemBugs.zip"
2. Build it to Android
3. Press "Button" in the middle of the screen
4. Notice the console appear on the top of the screen with the green word "INVOKE"

Expected results: "Can't invoke. Pressed on UI" red color message appears in the console
Actual results: "INVOKE" green color message appears in the console

Reproducible with: 2019.4.2f1(1.0.0), 2020.1.0b14(1.0.0), 2020.2.0a15(1.0.0)
Unable to test with: 2018.4 due to project braking

VLNQA00220, Samsung Galaxy Note9 (SM-N960F), Android 8.1.0, CPU: Exynos 9 Series 9810, GPU: Mali-G72
VLNQA00123, Google Pixel 2 XL (Pixel 2 XL), Android R, CPU: Snapdragon 835 MSM8998, GPU: Adreno (TM) 540
VLNQA00024, Xiaomi Mi 5 (MI 5), Android 7.0, CPU: Snapdragon 820 MSM8996, GPU: Adreno (TM) 530

Note: The button only reproduces when calling a public method directly, it will not reproduce if the method is called in the Update function, On some device both messages "INVOKE" and "Can't invoke" will be displayed but still this is unexpected

    [Mobile]Inconsistent results of EventSystem.current.IsPointerOverGameObject() across mobile platforms using the new Input System

  1. Resolution Note:

    IsPointerOverGameObject() will not return correct results when invoked from within action callbacks as input is processed before UI state is updated. The former happens before MonoBehaviour.Update()s are processed and the latter happens within MonoBehaviour.Update()s. Thus, polling IsPointerOverGameObject() from within action callbacks will rely on state from the last frame.
