Raycast made on UI with multiple graphic Raycasters sort strangely when being on the same sorting layer and order

uGUI

-

Steps to reproduce:
1. Open user-supplied project ("GraphicRaycaster2019.zip")
2. Enter Play mode in the Sample Scene
3. Notice the Console

Expected: the "Input Blocking Overlay" is called after "Front Button"
Actual: the order is reversed

Reproduced in: 2019.2.21f1, 2019.3.9f1, 2020.1.0b5, 2020.2.0a5

Note: User claims that this bug does not reproduce in 2018.4, you can check it with the attached project ("GraphicRaycaster2018.zip")
However, I cannot confirm that, since the 2019 project breaks when backported to 2018.4

  1. Resolution Note (2020.2.X):

    2018 project and 2019 project are not the same. The root canvas in 2018 has a GraphicRaycaster 2019 does not. The system requires the root raycaster as it uses that to determine which raycasters belong to one grouping of events. Without the root it counts each raycaster as its own hierarchy of objects and it will fall back to distance to object/ no sorting if everything is the same.
