ngrx/router-store crashes Chrome Redux DevTools Extension

[jongunter]

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?

1. Open Redux DevTools
2. Dispatch some non-router action. Everything works normally.
3. Navigate to a route by clicking a [routerLink]
4. Redux DevTools compleley freezes and stops working. ngrx is still working and there are no error messages printed in the console.

Expected behavior:

Redux DexTools should not freeze

Minimal reproduction of the problem with instructions:

See above for repro steps.
