    Summary:
    Check that force region simulation with Postsimulate works independently from rendering tick.

    Level Description:
    A Sphere is placed inside a Force Region. The "Fixed Time Step" in PhysX Configuration is set to 0.05.
    ForceRegion (entity) - Entity with PhysX Collider, PhysX Force Region (World Space force with magnitude 5.0) and
                           Box Shape components
    Sphere (entity) - Entity with PhysX Rigid Body, PhysX Collider, Mesh and 2 Script Canvas components
    Script Canvas:
    onpostphysicsupdate - The script checks the position of the sphere on every On Postsimulate event and prints
                          debug statements as per the position of the sphere relative to its previous position.
    ontick - The script checks the position of the sphere on every On Tick event and prints
             debug statements as per the position of the sphere relative to its previous position.

    Expected Behavior:
    The position of the sphere needs to be changed relative to its previous position for every
    OnPostPhysicsSubtick event.
    The position of the sphere sometimes change and sometimes remains in the same position as before
    for OnTick event.

    Test Steps:
     1) Open level
     2) Enter game mode
     3) Retrieve and validate entities
     4) Wait for WAIT_TIME for the events to occur
     5) Exit game mode
     6) Close the editor


    Note:
    - This test file must be called from the Open 3D Engine Editor command terminal
    - Any passed and failed tests are written to the Editor.log file.
            Parsing the file or running a log_monitor are required to observe the test results.
