patchRoutesOnNavigation is shortly rendering 404/NoMatch route when doing a hard refresh

[koen-dev]

I’m using patchRoutesOnNavigation with 25 Module Federated Microfrontends, and while it’s been a great improvement overall, I’ve encountered an issue. When a user directly navigates to a URL or performs a hard refresh for a route not in the default route tree, a 404/NoMatch page briefly displays before being replaced by the correct, patched route. Ideally, I’d like to show my global loading indicator during this time using the state from useNavigation() instead.

Is this behavior expected with patchRoutesOnNavigation, or is there an alternative approach to prevent the 404/NoMatch from rendering momentarily?

@brophdawg11 perhaps you have an idea on how to handle this? 😇

I have tried to reproduce this issue and wasn't able to do this exactly. Therefor this must be a side effect of my setup. I decided to switch to using the errorElement to render 404 pages and with the splat route gone this no longer happens. Apologies for the vague question without a reproducible repo.
