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)

Inizia riproducendo le asserzioni di launchFragmentInContainer, click e onView su API 30, confrontandole con API 21–29. Poi leggi il percorso di errore di RootViewPicker.java mostrato nello stack trace e analizza perché la radice della finestra di dialogo non ottiene mai il focus della finestra. Il lavoro è completato quando le asserzioni relative al titolo e al messaggio della finestra di dialogo passano in modo affidabile su API 30 senza introdurre regressioni negli altri livelli API testati.
