Description
### Description
Flaky Espresso.intended() won't find anything sometimes.
### Steps to Reproduce
Run the test proveEspressoIntendedIssue0 here: https://github.com/mobilekosmos/EspressoDialogsIssue/blob/master/app/src/androidTest/java/com/issues/espressoidling/MainActivity2Test.kt
The issue doesn't only happen because of using the loop, this is also happening when running the test manually, but difficult to reproduce when doing so, it works a few times, then it doesn't, therefore the loop where it was always reproducible till now on a Pixel 3a.
### Expected Results
Espresso.intended() shuould always find a view.
### Actual Results
Sometimes Espresso.intended() will hang and not find anything.
### AndroidX Test and Android OS Versions
Android R Preview 4
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

Research direction
Start by running proveEspressoIntendedIssue0 in app/src/androidTest/java/com/issues/espressoidling/MainActivity2Test.kt from the linked reproduction repository, using the listed AndroidX Test and Android R Preview 4 versions. Investigate why Espresso.intended() intermittently hangs or finds no view; done means the test reliably finds the expected view across repeated runs.
