Duplicate label error

[saket]

This is probably a weird edge case, but moshi-sealed doesn't like this setup:

@JsonClass(generateAdapter = true, generator = "sealed:type")
sealed interface Foo {

  @NestedSealed
  sealed interface SuperFoo : Foo

  @TypeLabel("real")
  data class RealFoo(…) : SuperFoo, Foo
}

Duplicate label 'real' defined for com.example.package.Foo.RealFoo and com.example.package.Foo.RealFoo.
