Parent navigation guard inconsistently re-run when redirecting between child routes about router

[pm0u]

Relevant docs explaining expected functionality: https://router.vuejs.org/guide/advanced/navigation-guards.html#Per-Route-Guard

[pm0u]

per the repro, seems to be isolated to when the redirect chain starts on initial "load". Notice it does not happen if the redirect chain is started from the router-link. Only the hard nav version

Since you are redirecting while entering on the first time, it has to trigger again each time you redirect. This is the correct behavior. After the first navigation to one of the children, it doesn’t re enter the parent so it doesn’t trigger again.

how is this the correct behavior? we are not re-entering the parent. We are entering a separate child

[pm0u]

Also, it doesn't always happen on the first redirect. Sometimes it happens on the 2nd or third which would not be "while entering."

Additionally, sometimes it doesn't happen at all. It also doesn't happen when the redirects are preceded by a router navigation. Is this difference expected?

See below for clarifications on the weird behavior

@posva

If that is the correct behavior, then this series of events shouldn't be possible, correct?

home beforeEnter
child1 beforeEnter
child2 beforeEnter
child3 beforeEnter
child4 beforeEnter

This is also reproducible randomly at the repro I shared.

[pm0u]

Seems to perhaps be an issue with the sandbox env. Opening in a new window, the logs I get are:

home beforeEnter
child1 beforeEnter
home beforeEnter
child2 beforeEnter
home beforeEnter
child3 beforeEnter
home beforeEnter
child4 beforeEnter

So, seems the inconsistency at least is due to the environment. But regardless, is this confirmed to be expected behavior that the parent nav guard would trigger before every single redirect?

If it is, then is it possible to accomplish a redirect from child to child without re-running the parent beforeEnter? If not, I think the docs should be updated as they seem to suggest that this would not be how the navigation guards would be handled.

[pm0u]

Following a router link to any of the "redirected to" examples does not trigger the parent before enter so this is an inconsistency with the handling of a router-link vs a redirect when going between siblings. I think at least the docs should be updated to clarify how these situations are handled differently if this is in fact the desired behavior
