[KSP2] KSClassDeclaration.getAllFunctions() doesn't return functions in the order they're declared

[BoD]

With 2.0.20-1.0.25.

Given a class like this:

class MyClass(private val c: Int) {
  fun a(){}
  fun b(){}
  fun c(){}
}

KSClassDeclaration.getAllFunctions() will return c, a, b, instead of a, b, c.

Removing or renaming the c val makes the order correct again.

This only happens with ksp.useKSP2=true.

Repro steps

git clone https://github.com/BoD/repro-ksp-getAllFunctions-order
cd repro-ksp-getAllFunctions-order
./gradlew build

Expected:
w: [ksp] all functions:[a, b, c, equals, hashCode, toString, <init>]

Actual:
w: [ksp] all functions:[c, a, b, equals, hashCode, toString, <init>]

Have you tried Resolver.getDeclarationsInSourceOrder?

This seemed promising, but surprisingly, I still have the wrong order with getDeclarationsInSourceOrder. I've updated my repro project here
