Working fine for me locally on API 28.

So the issue is that the current emulator binary sets the wear emulator to be connected to a charger. This causes the charger experience to cover the whole screen whenever the display goes to ambient.
The long term solution is to wait for a fix that is will be released which sets the wear emulator to not be on a charger by default.
The short term solution is to disconnect the charger before the test with adb emu power ac off

As @castedmo pointed out these are the View tests.

Running locally it generally works but there are still some timing issues or behavior change in the emulator breaking the test. Also in the compose test.

It will need someone to investigate and confirm the new behavior is a bug, or update the tests to be more tolerant if it's new expected behavior.
