To Reproduce Steps and/or the code snippet to reproduce the behavior:

@Composable
fun App() {
  MaterialTheme(
    colors = darkColors()

    Surface {
      Column(
        Modifier.statusBarsPadding().fillMaxSize(),
        verticalArrangement = Arrangement.Center
      ) {
        val focusManager = LocalFocusManager.current
        val imePadding = WindowInsets.ime.asPaddingValues()

        TextField("", {}, Modifier.fillMaxWidth())
        TextField("Hello World!", {}, Modifier.fillMaxWidth())
        Text(imePadding.toString())

        LazyColumn(
          Modifier.pointerInput(Unit) {
            detectTapGestures {
              focusManager.clearFocus(true)
            }
          }.imePadding()
        ) {
          items(100) {
