Shadow color has no effect on TextMeshPro (Unity 6)

[Nicolas-Red]

Describe the bug
Shadow color and color filter settings have no effect on TextMeshPro.
The shadow is always the same color as the text.
I'm on Unity 6000.0.28f1 and this is happening directly in the editor before even building.

To Reproduce
Steps to reproduce the behavior:

1. Create a TMPro Text.
2. Apply UI Effect.
3. Enable Shadow Outline.
4. Try Changing the Color to Black on a White Text.

Expected behavior
The shadow color should be what you set it to in the shadow settings.
