如何渲染 React.Suspense？

Question

我正在嘗試在空頁面上呈現 React.Suspense，但失敗並出現以下錯誤：

Uncaught Invariant Violation: Element type is invalid: expected a
string (for built-in components) or a class/function (for composite
components) but got: object.

這是代碼。 它編譯。 這是否意味着 scalajs-react 或 scalajs 不是 100% 類型安全的？ 我應該怎么做才能解決問題？

package org.myorg

import japgolly.scalajs.react.{AsyncCallback, React, ScalaComponent}
import japgolly.scalajs.react.vdom.html_<^._
import org.scalajs.dom

object MyPage {

  private val suspense = React.Suspense(
    fallback = <.div("Loading..."),
    asyncBody = AsyncCallback.point(<.div("Loaded!")).delayMs(1000))

  private val component = ScalaComponent.builder[VdomElement]("Home")
    .render_P(p => p)
    .build

  def main(args: Array[String]): Unit = {
    val container = dom.document.getElementById("app")

    // This line works
    component(<.div("hello")).renderIntoDOM(container)

    // Either of the following two lines fails
    component(suspense).renderIntoDOM(container)
    suspense.renderIntoDOM(container)
  }
}

這是項目文件。

build.properties：

sbt.version=1.2.7

構建.sbt：

lazy val root = project.in(file("."))
  .enablePlugins(ScalaJSPlugin)
  .enablePlugins(ScalaJSBundlerPlugin)
  .settings(
    organization := "org.myorg",
    scalaVersion := "2.12.8",
    scalaJSUseMainModuleInitializer := true,
    webpackBundlingMode := BundlingMode.LibraryOnly(),
    emitSourceMaps := false,
    npmDependencies in Compile ++= Seq(
      "react" -> "16.8.4",
      "react-dom" -> "16.8.4"
    ),
    libraryDependencies ++= Seq(
      "com.github.japgolly.scalajs-react" %%% "extra" % "1.4.0"
    ),
    jsEnv := new org.scalajs.jsenv.jsdomnodejs.JSDOMNodeJSEnv()
  )

索引.html：

<!doctype html>

這似乎是 scalajs-react 如何聲明其導入的問題。

v1.4.1 現在正在前往 Maven Central 的路上，應該會解決這個問題。
