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.
legacyRender(<ControlledInput />, container);
    utils.act(() => store.profilerStore.startProfiling());
    
    
    const setUntrackedValue = Object.getOwnPropertyDescriptor(
      HTMLInputElement.prototype,
      'value',
    ).set;
    const target = inputRef.current;
    setUntrackedValue.call(target, 'bar');
    target.dispatchEvent(new Event('input', {bubbles: true, cancelable: true}));
    expect(target.value).toBe('bar');
    utils.act(() => store.profilerStore.stopProfiling());
    
    const root = store.roots[0];
    const data = store.profilerStore.getDataForRoot(root);
    expect(data.commitData).toHaveLength(1);
    expect(data.operations).toHaveLength(1);
  });
  it('should throw if component filters are modified while profiling', () => {
    utils.act(() => store.profilerStore.startProfiling());
    expect(() => {
      utils.act(() => {
        const {
          ElementTypeHostComponent,
        } = require('react-devtools-shared/src/types');
        store.componentFilters = [
          utils.createElementTypeFilter(ElementTypeHostComponent),
        ];
      });
