Is there a way to detect the open suggestions drop-down state of the Autocomplete component?

[davidrhoderick]

We are trying to test this component as part of our application with Cypress and currently, the only way to test the Autocomplete is to manually set a wait for the drop-down to show. Is there any kind of state we can hook into for this? We want to be able to detect when the suggestions drop-down appears. I was able to see the .pac-containers elements at the bottom but there are always at least 2 and I couldn't easily grab the open one from within the React app.
