Typealias annotation parameters are resolved as "alias target", not the type alias itself

[sebek64]

Typealias annotation arguments are resolved before provided to ksp:

typealias MyAlias = Map<String, String>

@SomeAnnotation(
    param = MyAlias::class,
)
...
val type: KSType = annotation.arguments.first().value as KSType
check(type.declaration is KSTypeAlias) {
    "Not the typealias itself" // this error is thrown - type is already the Map<*, *> (without correctly solved type parameters, but only with star projections)
}
