Espresso Tests fail on Android 11

### Description
I have integration tests running from API 21 to API 29. I've been trying to update our app to target API 30 but the tests are flaky just on API 30.

### Steps to Reproduce
1. I have a simple case where I tap on a button that should popup a dialog
```kotlin
btnDialog.setOnClickListener {
MaterialAlertDialogBuilder(this).apply {
setTitle("Test Dialog")
setMessage("This should work on API 30")
setPositiveButton(android.R.string.ok, null)
create()
}.show()
}
```

2. Then I try to test it via:
```kotlin
// Given - fragment is launched
launchFragmentInContainer(...)

// When - the button is clicked
onView(withId(R.id.btn_dialog)).perform(click())

// Then - dialog with message should be shown
onView(withText("Test Dialog")).check(matches(isDisplayed()))
onView(withText("This should work on API 30")).check(matches(isDisplayed()))
```
* I also tried using `RootMatchers.isDialog()` but the same behavior.

### Expected Results
This works perfectly from API 21 to API 29. It should also work in API 30. I also turned off all the compatibility changes just to check and it still is happening.

### Actual Results
Runtime Exception:
```kotlin

### AndroidX Test and Android OS Versions
AndroidX Test: 1.3.0
Espresso: 3.3.0
Android OS: Android 11 (API 30)

Commencez par reproduire les assertions launchFragmentInContainer, click et onView sur API 30, en les comparant avec API 21–29. Lisez ensuite le chemin d’échec de RootViewPicker.java indiqué dans la stack trace et cherchez pourquoi la racine de la boîte de dialogue n’obtient jamais le focus de la fenêtre. Le travail est terminé lorsque les assertions du titre et du message de la boîte de dialogue passent de manière fiable sur API 30 sans provoquer de régression sur les autres niveaux d’API testés.
