KSType.toTypeName() is inaccurate when typealias are mixed.

[nazoking]

When a type aliased as a generic type has a type parameter, the result of method KSType.toTypeName() outputs an incorrect type name and type parameter.

The following pattern is as expected.

// on code,
typealias Alias2<X> = Map<X, Int>
lateinit var n3: Alias2<String>

// and in ksp processor,
resolver.getPropertyDeclarationByName("n2", true)!!.type.toTypeName().toString()
// expected:  `Alias2<String>`  , equals actual: `Alias2<String>` 

However, the next two patterns are incorrect

// on code,
typealias Alias = List<Int>
val n: List<Alias>

// and in ksp processor,
resolver.getPropertyDeclarationByName("n", true)!!.type.toTypeName().toString()
// expected:  `List<Alias>`   , but actual: `List<Alias<Int>>` 

// on code,
typealias Alias2<X> = Map<X, Int>
lateinit var n2: List<Alias2<String>>

// and in ksp processor,
resolver.getPropertyDeclarationByName("n2", true)!!.type.toTypeName().toString()
// expected:  `List<Alias2<String>>`   , but actual: `List<Alias2<String, Int>>`

oh..?

I just ran your test file with my test code and run it, I get different results than what you report above. ( The results were output as expected. )
I will look into this a little more. Please let me know if you can give me any hints.
My test environment is
jdk version is 14
gradle is 7.2.

ok.

The cause was found.
The problem I faced was one that was fixed by the pull request #1321 .
This fix has not yet been released and has not been incorporated in the version 1.20.0 I am testing.
I close this Issue.
I look forward to a release in the near future.
Thanks for a great library.
