Reproduction steps:
1. Open the attached “Test_TMPro_styles.zip” project
2. Open the “SampleScene” scene
3. Observe the “Text_1” and “Text_2” TextMeshPro GameObjects

Expected result: Both GameObjects look the same
Actual result: “Text_1” GameObject does not have Text Style applied to Strikethrough and Underline Font Styles

Reproducible with: 2021.3.40f1, 2022.3.37f1, 6000.0.10f1

Reproducible on: Windows 11

Notes:
- The issue is reproducible with most Text Styles (except “Normal”, “Quote” and “Title”)
- The issue does not reproduce if tags “<s>” or “<u>” are used, like in “Text_2” GameObject
