Toast message assertions not working with android 11 and target sdk 30

### Description
On the app I am testing there are a number of toast messages that I check to make sure toasts are displayed with correct text. My espresso tests started to fail when using Android 11 and SDK30.

### Steps to Reproduce
I have a simple check where I try to check the text appears on screen for a toast.
`onView(withText(R.string.toast_text)).inRoot(
withDecorView(not(activityRule.activity.window.decorView)))
.check(matches(isDisplayed()))`

I have also tried with a Custom toast matcher without any luck

fun onToast(
text: Int,
@IntRange(from = 1) maximumRetries: Int = MAX_RETRIES
): ViewInteraction = onView(withText(text)).inRoot(ToastMatcher(maximumRetries))

class ToastMatcher(private val maximumRetries: Int) : TypeSafeMatcher() {

private var currentFailures: Int = 0

override fun describeTo(description: Description?) {
description?.appendText("no toast found after")
}

override fun matchesSafely(item: Root?): Boolean {
val type: Int? = item?.windowLayoutParams?.get()?.type

if(TYPE_TOAST == type || TYPE_APPLICATION_OVERLAY == type) {
val windowToken = item.decorView.windowToken
val appToken = item.decorView.applicationWindowToken

if(windowToken == appToken) {
return true
}
}

return ++currentFailures >= maximumRetries
}
}

`onToast(R.string.toast_text)
.check(matches(isDisplayed()))`

### Expected Results
Tests pass.
This works as expected when using OS lower than android 11. It also works as expected when using android 11 and sdk 29.
I also tried updating the version of androidx and espresso to the latest version 3.3.0 and 1.3.0 but this did not make any difference.

### Actual Results
Result when using withDecorView
`androidx.test.espresso.NoMatchingRootException: Matcher 'with decor view not ' did not match any of the following roots: [Root{application-window-token=android.view.ViewRootImpl$W@1337585, window-token=android.view.ViewRootImpl$W@1337585, has-window-focus=true, layout-params-type=1, layout-params-string={(0,0)(fillxfill) sim={state=hidden} ty=BASE_APPLICATION wanim=0x10302fe

### AndroidX Test and Android OS Versions
AndroidX Test: 1.2.0
Espresso: 3.2.0
Android OS: Android 11 (API 30)

Riproduci l’assertion del Toast con Espresso su Android 11/API 30 e target SDK 30, utilizzando gli esempi mostrati di withDecorView e ToastMatcher. Inizia esaminando la gestione delle root di Espresso e dei Toast in relazione a questi matcher; il lavoro è completo quando un test di regressione trova in modo affidabile il Toast, preservando al contempo il comportamento sulle versioni precedenti di Android.
