History pushState doesn't trigger Interceptor Route

[iamJoeTaylor]

Link to the code that reproduces this issue

https://github.com/iamJoeTaylor/next-intercept-route

To Reproduce

1. Using my repro you can npm run dev in my-app
2. Click on Open Modal with history which uses window.history.pushState

To build a reproduction yourself;

1. New NextJS project with App router.
2. Add an Interceptor Route
3. use window.history.pushState

This blog mentions pushSate so I'd expect it to work. https://nextjs.org/blog/next-14-1#windowhistorypushstate-and-windowhistoryreplacestate

Current vs. Expected behavior

Currently the URL changes but the interceptor route is not invoked.

Expect the URL to change, the intercept route to work, and the history item to be present when fetched from window.history.state
