Async mode prevents afterNavigate from running at mount

[bleucitron]

Describe the bug

afterNavigate will not run on mount if async is on.

It should be noted that client navigations will result in afterNavigate running. The issue is only during mounting.

I see no problem.

When running your reproduction I see

SHOULD BE DISPLAYED ON MOUNT

being logged to the console.

I'm sorry, the link was incorrect, it pointed to the non-async version, which works correctly.

The repro should be fine now.
