In short, the Java package does not exist in Javascript mode. You will have to do it in JVM mode for now. The class should just use children = mutableListOf<Tag>() and it would work by default. There is even a kotlin version of arraylist that will work in Javascript. If you want you can file a bug in youtrack to get this updated.
