Steps to Reproduce

With ktlint 0.42.0, the following fails when formatting:

class ApplicationContextSpec(private val applicationContext: ApplicationContext) : BehaviorSpec({
    Given("something") {
        When("run") {
            Then("it should do something") {
                applicationContext.getBean(Bean::class.java) shouldNotBe null
            }
        }
    }
}) {
    @MockkBean
    lateinit var other: OtherBean
}

Thanks for the report @cldfzn. Can you confirm this is new in 0.42.0?

[cldfzn]

Yeah, I was testing out the upgrade from 0.41.0 to 0.42.0.

I'm planning on a 0.42.1 release since this was a regression introduced to 0.42.
