`sleep` does not work when a `DialogFragment` is open and the test is running on Android 11+

Library Version:

4.3.0

Describe the Bug:

When calling sleep while a DialogFragment is open, the test fails every time on Android 11+ with an error "Waited for the root of the view hierarchy to have window focus and not request layout for 10 seconds"

I believe this may be related to issue android/android-test#751
In the code, sleep is calling isRoot to look for the root view, but this doesn't work properly if a DialogFragment is open.

Steps to reproduce the bug:

1. Open a DialogFragment, for example I'm using a BottomSheetDialogFragment
2. After it opens, call sleep
3. See that the test fails

Expected Behavior:

I expected sleep to work as normal.

One option might be to be able to pass a view matcher to sleep, which could be of a view you know to exist. Or else just match any view using some generic matcher like withClassName(any()) or something.
