As far as I can tell enzyme is simply not supporting this (yet). Happy to start working on a PR that adds this to the mount API.

I'm personally not that interested in shallow rendering. I guess we would need to establish first how the Profiler should work with shallow rendering.

This should also be included in #1553.

You’re correct, it doesn’t yet. A PR would be great!

(and yes, to be added to mount we’d need to decide what the behavior is for shallow, and ideally it’d be identical)

I'd say this is closed by #2055.
