RBuilderSingle is not a constructor

[skrabbenborg]

A simple test I've written could not be executed due to TypeError: RBuilderSingle is not a constructor.

dependencies {
    ...
    implementation("io.github.mysticfall:kotlin-react-test:1.2.0")
}

import kotlin.test.Test
import mysticfall.kotlin.react.test.ReactTestSupport
import react.dom.html.ReactHTML.div

class Test : ReactTestSupport {

    @Test
    fun test() {
        val renderer = render {
            div {
                +"Test"
            }
        }
    }
}

Any idea what i'm doing wrong here?
