Not sure about this error
```Smart cast to 'LinkOrigin.ActionButtonLink' is impossible, because 'event.origin' is a public API property declared in different module```
`LinkOrigin` is sealed class in the different module indeed. But why is it the problem?

It's because the `origin` property is defined in a different module, which is separately compiled, and therefore the compiler can't be sure that repeated accesses of this property will return the same value.

You mean that it doesn’t have kotlin meta data or this bytecode is java and could be changed?

A separately compiled module can be Kotlin or Java code, and in both cases smart casts are not applied on properties. I'm not sure if the Kotlin metadata on a property says whether or not it can return a different value between calls. But certainly a Java getXxxx() method can.

Thank you. I don’t remember it being the case before. Some inconvenience for sure.
