Seems like the fix for MC-263338 and MC-259982 caused most, if not all armor trims applied on chainmail armor to look very different to how they did in 1.20.1. This seems like a remarkable downgrade for a pretty minor fix for some floating pixels in the chainmail helmet, and makes this especially noticeable on the silence and vex armor trims.

For players that already have these trims in worlds made in 1.20.1 might find this very concerning, as these changes weren't stated in the 23w32a changelog.

Expected result
Armor trims changes would only account for those cases stated in MC-259982, and the rest would remain unchanged, as there weren't floating pixel issues there (unless you interpret overhanging pixels outside the base texture as floating even if they connect somehow, like in the vex trim texture).

Observed result
Several pixels on the chainmal armor trims have been removed, which seems like a notable downgrade from 1.20.1.

How to reproduce

1. Create a world in 1.20.1 or 23w31a and make a chainmail armor with the vex and silence armor trims.
2. Notice how the texture looks.
3. Exit the world and upgrade it to 23w32a.
4. Notice how the armor trims look significantly different now.
