I'm struggling to make an isolated example of this, but the app where I found this is pretty simple so hopefully it's not too challenging to track down.

So I was profiling https://the-react-bookshelf.netlify.com (locally) and got this when I clicked on the "login" button:

The fact that there was no profile data for a commit is interesting. Each commit should be associated to a state update somewhere in the tree, and wherever that happened should trigger at least one component to re-render, but that didn't appear to happen here.

I also verified that I don't have any components filtered out:

And I didn't filter any commits either:

Here's the exported profile data:

And here's the repo where you can pull it down and reproduce yourself: https://github.com/kentcdodds/bookshelf. The component we're looking at is here: https://github.com/kentcdodds/bookshelf/blob/master/src/unauthenticated-app.js

Sorry I can't give a more direct reproduction.
