Description
Certain combinations of transition properties get built into a longer form. I was able to get this behavior just from using lightningcss as a minifier.
Example input:
.foo {
transition: 0.2s cubic-bezier(0.4, 0, 0.2, 1);
transition-property: height, width, transform, max-width, left, right, top, bottom, box-shadow;
}
If I could get a couple code pointers, I'd love to contribute a fix for it.

Research direction
Start with the CSS example in the issue and reproduce it through the linked Lightning CSS Playground with minification enabled. Trace how the minifier handles the combination of transition and transition-property; done means the input is no longer incorrectly expanded into the reported longer form, with a regression test covering the example.
