Toggle checkmark image is rendered after re-enabling the Image Component when Is On setting is set to false

uGUI

-

How to reproduce:
1. Open the attached project
2. Open AbstractColorFilterToggle prefab
3. Select Checkmark in the Scene Hierarchy
4. Disable and enable the Image component

Expected result: The Checkmark image is not visible
Actual result: The Checkmark image becomes visible after enabling the component

Reproducible with: 2018.4.33f1, 2019.4.23f1, 2020.3.2f1, 2021.1.2f1, 2021.2.0a12

Notes:
1. The issue will fix itself when entering play mode, reloading the scene, or prefab
2. The issue is reproducible when enabling/disabling the Checkmark GameObject
3. The issue is reproducible when the Toggle Is On is set to false in the saved Scene/Prefab

  1. Resolution Note:

    We dont have a mechanism to track the enabled state of the child image component. As the system works off changing the alpha of the CanvasRenderer to 0, and calling OnDisable resets the color back to 1, upon enable we dont have a callback to reset the state.

    If disabling the image component is something the user needs they would be required to check the state of the toggle.
