test: remove invalid css that was causing issues with the postcss parser

mattrbeck · mattrbeck · commit baf92da96ed7 · 2026-05-07T15:20:20.000-07:00
These tests happened to use garbage "{c}" declaration lists which caused the parser to choke. Given that we already have tests demonstrating similar behavior and that's not what these tests were meant to demonstrate, I've updated them to use empty declaration lists. (cherry picked from commit b1699da)
