Vertical mapping of most characters is incorrect when using a Texture on each character

How to reproduce:
1. Open the “TextMeshProBugs.zip“
2. Open the “TestUvMapping Vertical MatchAspect“ Scene
3. Observe the Scene view

Expected results: All characters are uniformly affected by the texture, and feature only one cycle of the texture
Actual results: Characters m, M, w, and W feature only one cycle of the texture, while the other characters have noticeably more cycles of the texture applied

Reproducible in: 2021.3.37f1, 2022.3.26f1, 2023.2.20f1, 6000.0.0f1

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:

• Each character has a different texture stretch to it
• All horizontal with “Line“ vertical mapping combinations result in g, j, p, q, and y characters being affected
• All other combinations seem to be working correctly
