Time travel debugging with Redux DevTools not working

[scriby]

I'm submitting a...

[ ] Regression (a behavior that used to work and stopped working in a new release)
[x] Bug report
[ ] Feature request
[ ] Documentation issue or request

What is the current behavior?

Clicking the "jump" button in the Redux DevTools has no effect on the app. The behavior is the same in both an app I am developing and in the [example app](git clone https://github.com/ngrx/platform.git).

Expected behavior:

The Redux DevTools work as they do when using them with a react + redux application.

Minimal reproduction of the problem with instructions:

1. Install and run the [example app](git clone https://github.com/ngrx/platform.git) locally
2. Install the redux devtools
3. Browse to http://localhost:4200, open the redux devtools, and verify it connected to the store
4. Log in with test/test and search for some books
5. In the redux devtools, click the "jump" button on any of the actions
6. Observe that time travelling did not actually take place

Version of affected browser(s),operating system(s), npm, node and ngrx:

Chrome 63, Linux, npm 5.5.1, node v8.9.1, ngrx v4.1.1

Other information:

I have had success with the "skip" button working. Persisting state is similarly broken as jump is.
