What I should do with polymorphic class in JS module? I have custom serializer. With `0.5.0` it worked well. With `0.6.0` compile is crashing with `Can't locate polymorphic serializer definition`

Polymorphic serializer wasn’t available in JS on 0.5.0. Can you explain your problem in details in. e.g., GitHub issue?

I am not sure, probably it is my problem. I have an entity with: 
```
val planets: List&lt;Container&lt;Planet&gt;&gt; = emptyList()
```

And I have custom serializers in JS and JVM modules

Custom serializer is very simple, it serializes only ID

If I define:
```
    @Serializable(with = ContainerSerializer::class)
    val planets: List&lt;Container&lt;Planet&gt;&gt; = emptyList(),
```

Compiler works, but field is serialized with `ContainerSerializer`

So, if I understand correctly, `0.6.0` version does check `polymorphic fields` for JS module and leave no chance to use custom serializer.

Here is it: <https://github.com/Kotlin/kotlinx.serialization/pull/176>
