[Shader Graph] Shaders from Shader Graph don't work on UI with Canvas "Render Mode" set to "Overlay"

Package: Shader Graph

-

Reproduction steps:
1. Open "1193291" project
2. Notice that the Image has Perlin Noise
3. Select the "Canvas" Game Object -> "Canvas" -> "Render Mode" and change it to "Screen Space - Overlay"
4. Notice that the Image is now Black

Expected Result: Shader Graph Shaders should render properly with every Canvas "Render Mode"
Actual Result: Setting the "Render Mode" of the Canvas to "Overlay" doesn't render Shader Graph Shaders on Images

Reproduced with: 2020.1.0a9, 2019.3.0b8, 2019.2.10f1, 2018.4.12f1
Did not reproduce on: 2017.4.33f1 (No Packman)

  1. Resolution Note:

    As of 2020.1 and earlier, Shader Graph does not officially support UI shaders. The feature request is on our roadmap.

    It's broken even today

    I would really appreciate a fix for this as well. SG unlit sprite shaders now go bonkers when you set alpha on a parent CanvasGroup below 1. Transparency turns up as red opaque.

    Just chiming in, this is kinda important for me as well.

    ShaderGraph shaders used to work in 2021.1.20f1. But now, after upgrading to 2021.2.12f1, they ceased to work and render all alpha black, which is a gamebreaking bug for us, rendering this Unity version unusable.

    Why is this issue marked as "By Design", since it clearly worked before?

    Interesting, is it even an option to add SG's to UI elements in some limited capacity?
    I understand the limiting factor is the lack of a proper camera in SS:Overlay?

    I cant see it on the roadmap. Is this not a fairly simple fix for something kinda important?
