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.
} else {
      forceFallbackForSuspenseIDs.delete(id);
      if (forceFallbackForSuspenseIDs.size === 0) {
         L
        setSuspenseHandler(shouldSuspendFiberAlwaysFalse);
      }
    }
    const fiber = idToArbitraryFiberMap.get(id);
    if (fiber != null) {
      scheduleUpdate(fiber);
    }
  }
   Remember if we're trying to restore the selection after reload.
   In that case, we'll do some extra checks for matching mounts.
  let trackedPath: Array<PathFrame> | null = null;
  let trackedPathMatchFiber: Fiber | null = null;
  let trackedPathMatchDepth = -1;
  let mightBeOnTrackedPath = false;
  function setTrackedPath(path: Array<PathFrame> | null) {
    if (path === null) {
      trackedPathMatchFiber = null;
      trackedPathMatchDepth = -1;
      mightBeOnTrackedPath = false;
    }
    trackedPath = path;
  }
   We call this before traversing a new mount.
   It remembers whether this Fiber is the next best match for tracked path.
   The return value signals whether we should keep matching siblings or not.
  function updateTrackedPathStateBeforeMount(fiber: Fiber): boolean {
