Font Rendering: SDF Kerning and vertical Tracking incorrect

[thygrrr]

Release Type: Official 4.2

Version: 4.2.0.2067 on .NET 8.0.2

Platform(s): Windows 11

Describe the bug
Font kerning/tracking for SDF fonts is incorrect, letters are squished together and letters dance up and down on each line.

To Reproduce

1. download font Baj Jamjuree from Google Fonts
2. create SDF font, size 20 or 24
3. create a text block and zoom in (sometimes easier to see at runtime)

In editor (red annotation to show the vertical issues)

At runtime:

Expected behavior
Kerning is as defined and hinted in the font. Tracking and scanning is as defined and hinted in the font.
