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)

Start by reproducing the launchFragmentInContainer, click, and onView assertions on API 30, comparing them with API 21–29. Then read the RootViewPicker.java failure path shown in the stack trace and investigate why the dialog root never gains window focus. Done means the dialog title and message assertions pass reliably on API 30 without regressing the other tested API levels.
