Support for Accessibility Containers

[cnstoll]

Hi! I was wondering if ya'll have considered support for Accessibility Containers. The main reason I ask is that containers can have an accessibility label and custom actions that are still read even though the container itself isn't a focusable accessibility element. I feel like it would be useful to having that data in the snapshot images. I might be able to implement this change, but I wanted to know if ya'll have considered it or if there's any reason it wasn't implemented already. Thanks!
