[TextMeshPro] A lot of submesh children are created when a specific text is displayed
Reproduction steps:
1. Open the attached “ExampleProject” project
2. Open the “Assets/Scenes/SampleScene” scene
3. Enter the Play mode
4. Press the “1” key
5. Observe the “Submeshes” count in the top left corner of the Game view
Expected Result: The “Submeshes” count is small
Actual Result: The “Submeshes” count is over 1400
Reproducible with: 2021.3.41f1, 2022.3.39f1, 6000.0.12f1
Reproducible on: Windows 11 Pro
Not reproducible on: No other environments tested
Notes:
- Pressing the “2” key instead of the “1” key shows the expected behavior
- The main difference between the two loaded text files is the first ten lines
