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)

Bắt đầu bằng cách tái hiện các assertion của launchFragmentInContainer, click và onView trên API 30, rồi so sánh chúng với API 21–29. Sau đó đọc đường dẫn lỗi của RootViewPicker.java được hiển thị trong stack trace và điều tra lý do root của dialog không bao giờ nhận được window focus. Được xem là hoàn tất khi các assertion về tiêu đề và thông báo của dialog vượt qua ổn định trên API 30 mà không gây regression ở các API level khác đã được kiểm thử.
