WebView crashing on input when used with Jetpack Compose

Question

When creating a dead-simple WebView wrapper with Jetpack Compose, the app crashes the second I enter any text. Is this a bug, or am I doing something stupid? The relevant code:

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            WebViewC()
        }
    }
}

@Composable
fun WebViewC() {
    return AndroidView(viewBlock = { context ->
        WebView(context).apply {
            layoutParams = ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT
            )
            webViewClient = object : WebViewClient() {
                override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
                    return false
                }
            }
            loadUrl("https://google.com")
        }
    })
}

The crash:

E/MessageQueue-JNI: java.lang.IllegalStateException: KeyEvent can't be processed because this key input node is not active.

If you want to dynamic change url you need to add update method too.

@SuppressLint("SetJavaScriptEnabled")
@Composable
fun WebPageScreen(urlToRender: String) {
  AndroidView(factory = {
    WebView(it).apply {
      layoutParams = ViewGroup.LayoutParams(
          ViewGroup.LayoutParams.MATCH_PARENT,
          ViewGroup.LayoutParams.MATCH_PARENT
      )
      webViewClient = WebViewClient()
      loadUrl(urlToRender)
    }
  }, update = {
    it.loadUrl(urlToRender)
  })
}

It appears that this was in fact a bug in Compose. Updating to the newest version (alpha09 at the time of this answer) seems to have fixed the issue for me.
