bug: `_` suffix (layout exclude) renders the layout

[tresorama]

Which project does this relate to?

Router

Describe the bug

Here is a Codesandbox that you can open to see the issue.

AFAIK from the docs:

_ Suffix | Route segments with the _ suffix exclude the route from being nested under any parent routes.

But you can see that Layout Red - Page B, even if the filename is _layout-red.page-b_.tsx (with _ suffix) still render the layout.

Your Example Website or App

https://codesandbox.io/p/devbox/h928ss

Steps to Reproduce the Bug or Issue

1. Open Sandbox
2. Click on Sidebar > Home and look a page without a layout
3. Click on Sidebar -> Layout Red Page A and look a page under layout red
4. Click on Sidebar -> Layout Red Page B and look the affected page, that should not render the layout but it does

Expected behavior

_layout-red.page-b_.tsx should not rendere the layout _layout-red.tsx

in your example it would need to be _layout-red_.page-b.tsx to exclude page-b from the layout. un-nesting does not make much sense for layout routes though, this feature is meant for the case where you want the path to contain some segment but don't want to nest under the route that defines this path segment

Thanks for the hint.
So the suffix must be used on layout segment only .

I think this should be in the docs
