TextMeshPro Inverse Masking Shape (Substract) Not Working

[ndumais]

Describe the bug
On version 3.0.1 (and possibly the ones prior), adding a masking shape to a GameObject with TextMeshPro (UI) component does not seem to work as expected.

I've made sure the TextMeshPro (UI) shows properly by putting it underneath in the hierarchy and removing the Masking Shape. Note that the mobile hidden soft mask shader for text mesh pro is being used and visible in the inspector (see 2nd screenshot).

To Reproduce
Steps to reproduce the behavior:

1. Import TextMeshPro support from the package manager.
2. Make a parent image with SoftMask component (and uncheck show mask graphic).
3. In childrens, add a normal text with a Masking Shape (and set to substract).
4. Still in childrens, add the image that will be masked by the text.
5. It works, the text masks the image (see 1st screenshot).
6. Add a TextMeshPro (UI) Component in the same way the Unity Text was added (you can remove disable the Unity Text).
7. Does not work.

Screenshots

Expected behavior
TextMeshPro UI with a shaping mask should behave as Unity Text if TextMeshPro support is imported.

Environment (please complete the following information):

• Version 3.0.1
• Platform: Editor (Windows)
• Unity version: 2022.3.50f1
• Build options: .Net 2.1

Thank you for your reporting!
Could you please attach a minimal project (included Assets, Packages and ProjectSettings directories) that reproduces the issue?
Of course, you don't need to include any secret assets from your project. Feel free to use free assets instead.

Just created a new project with the two examples side by side
