How can I keep the previous page when a loader throws?

[ClementDreptin]

Hey,

I would like to keep the previous page when a loader throws during navigation.

Let's say I have 2 routes: / and /about. And /about has a loader that might throw. I would like to stay on / and display the error in some way, like a toast for example.

I thought I could do this by providing an onError callback to my /about route, but I need to provide an errorComponent if I don't want the default one to show, which will override the content of my / route.

What lead me to believe the navigation would be cancelled was the following phrase from the documentation.

If thrown during a navigation, the navigation will be cancelled and the error will be passed to the onError function.

Am I missing something or is this kind of behavior not supported right now?
