Improve support for overlapping dynamic routes with `validate()`

[lulcca]

Environment

Nuxt Version: 3.15.4

Reproduction

https://stackblitz.com/edit/github-jeicynwl

Describe the bug

Nuxt documentation says that, when returning false in validate, it will check for other possibilities; but this does not happen, we receive a 404 page not found error.

Am I doing something wrong?

This seems to be related to your file structure. From the Nuxt DevTools, it appears that the corresponding route configuration only matches [slugOne].vue, but not [slugTwo].vue, based on your current file structure.

[lulcca]

A and B should match [slugOne].vue, C and D should match [slugTwo].vue

same display if I had a catch-all route

if I make [slugOne].vue optional, i.e [[slugOne]].vue, it starts matching [slugTwo].vue primarily and we get the opposite behavior (C and D become valid routes, A and B throws page not found error).

this seems more like an issue with vue-router to me
