Two interfaces with the same name always return the latter one in Kotlin/Wasm

[fhilgers]

Describe the bug
Registering two interfaces with the same name, but from different namespaces (e.g. TestClass1.SameName and TestClass2.SameName) always returns the last of the registered implementations. This only happens in Kotlin/Wasm.

To Reproduce
Run the sample snippet below and observe the console.

The console will show TestClass2SameNameImpl@... instead of TestClass1SameNameImpl@....

Expected behavior
Return an implementation of the requested interface, not the last one.

Koin module and version:
koin-bom:4.0.0 with koin-core

Snippet or Sample project to help reproduce

package org.example.project

import org.koin.core.context.startKoin
import org.koin.dsl.koinApplication
import org.koin.dsl.module

class TestClass1 {
    interface SameName
}

class TestClass2 {
    interface SameName
}

class TestClass1SameNameImpl : TestClass1.SameName
class TestClass2SameNameImpl : TestClass2.SameName

val myModule = module {
    single<TestClass1.SameName> { TestClass1SameNameImpl() }
    single<TestClass2.SameName> { TestClass2SameNameImpl() }
}

fun koinConfiguration() = koinApplication {
    modules(myModule)
}

fun main() {
    val koin = startKoin(koinConfiguration())
    val x = koin.koin.get<TestClass1.SameName>()
    println(x) // Will print TestClass2SameNameImpl even though we requested TestClass1.SameName
}
