The H1 style as defined in the Default StyleSheet is expected to append "*". Note that the Default StyleSheet can be edited and the "*" can be manually removed.
Steps to reproduce:
Create a new project.
Hierarchy > UI > Text - TextMeshPro. Install TMP Essentials when prompted.
Focus on the created text in scene view.
In the inspector, set Text Style to H1.
Actual results: Text changes formatting, and is surrounded by asterisks.
Expected results: Text changes formatting, but no asterisks display. Similar to H2 and H3.
Reproducible with versions: 6000.0.7f1, 2022.3.33f1, 2021.3.38f1
