Nested Canvases with Override Sorting enabled will not sort correctly until closing and reopening the project



How to reproduce:
1. Create a new Unity project
2. Add a Canvas to the Scene
3. Create a child Inherit Canvas with Override Sorting enabled
4. Create a child Image and add a Canvas component with Override Sorting to it
5. Set the Image color to red
5. Create another child Image and add a Canvas component with Override Sorting to it
6. Set the Sorting Order to 1
7. Enter Play Mode

Expected result: You see a White Image
Actual result: You see a red Image

Reproducible with: 2018.4.34f1, 2019.4.25f1, 2020.3.6f1, 2021.1.5f1, 2021.2.0a15

Workaround: Update the red Image Override Sorting via code

1. This only reproduces the first time this setup is created. If you close and reopen the project the Images render correctly
2. If you disable and enable the parent Canvas or change the sort order in Playmode the issue is fixed

  1. Resolution Note (fix version 2022.2):

    I am also experiencing this issue in 2021.3.16f1. Are you guys going to fix this in 2021 LTS version? Kind of important and don't really want to go to 2022 just for this.

    The workarounds aren't really possible for me as the only thing I could think of that fixes it temporarily is changing sorting order after first frame, but the UI flashes all messed up for a frame and it is very jarring...
