Incorrect Preferred Height calculation when a single text line uses different Font Assets

Reproduction steps:
1. Open the attached “IN-99300.zip” project
2. Open the “Test” Scene
3. Observe the Game view

Expected result: All of the text has the correct height and is fully shown
Actual result: Text fields above the “x” symbol have incorrect height and have “…” written instead of text

Reproducible with: 2022.3.61f1, 6000.0.48f1, 6000.1.1f1, 6000.2.0a10

Reproducible on: Windows 10 (User reported), Windows 11
Not reproducible on: no other environment tested

Notes:

• Does not reproduce if the Fallback Font is selected as the main Font Asset
• Issue reproduces when a single text line contains ​at least two different TMP SubMeshUI components (e.g., mixed SDF fonts or FallbackFontAssets)
• Layout likely fails due to incorrect aggregation of Ascender/Descender/LineOffset metrics from these different components
