BehaviorSpec run parallel?

When I execute this BehaviorSpec, the upper when block always fails (even when I swap those two). the upper block assignment is always overridden by the latter. Is this an issue or I just misunderstand spec flow?

given("user) {
val user = User()

  `when`("set valid email") {
    user.email = VALID_EMAIL
    
    then("should get correct email") {
      user.email shouldBe VALID_EMAIL
    }
  }
 
  `when`("set null email") {
    user.email = null
      
    then("should get null email") {
      user.email shouldBe null
    }
  }

This is fixed in 3.0.0 RC1. If you have the time, please give it a try. There are some breaking changes that should be aware of by reading the changelog here: https://github.com/kotlintest/kotlintest/blob/master/CHANGELOG.md

The issue is, the when block has to be executed in order to discover the then block nested inside. However, this means the side effects (setting user.email) overwrite each other.
