Bug description

Cascade property affects the next page with similar name.
We use cascade in one of our pages (/team) to prevent rendering its children separately. But the cascade property affects the next following page (/teams).

File setup

/content
├ /de
│├ /...
│├ /team (List of our employees)
││├ /employee_1
│││└ index.md
││├ /...
││└ _index.md
│├ /teams (Articles about Microsoft Teams)
││├ /article_1
│││└ index.md
││├ /...
││└ _index.md
│├ /...
...

Code

/content/de/team/_index.md:

...
cascade:
    _build:
        render: never
_build:
    render: always
---

Tests

1. Renaming the folder "/teams" to "/xteams"
   → "/xteams" was rendered
2. Put the same cascade properties pages where the next page had an similar name
   → E.g. cascade properties were added to "/microsoft" and the next page ("microsoft-365") wasn't rendered anymore

Conclusion

Cascade should only affect children of an page.
→ /page/...
But cascade affect every page where the name starts with the name of the page with the cascade properties.
→ /page...

This problem was introduced in v0.123.0. Failing test:

func TestFoo(t *testing.T) {
	t.Parallel()

	files := `
-- hugo.toml --
disableKinds = ['home','rss','sitemap','taxonomy','term']
-- layouts/_default/list.html --
{{ .Title }}
-- layouts/_default/single.html --
{{ .Title }}
-- content/s/_index.md --
---
title: s
cascade:
  _build:
    render: never
---
-- content/s/p1.md --
---
title: p1
---
-- content/sx/_index.md --
---
title: sx
---
-- content/sx/p2.md --
---
title: p2
---
`

	b := hugolib.Test(t, files)

	b.AssertFileExists("public/s/index.html", false)
	b.AssertFileExists("public/s/p1/index.html", false)

	b.AssertFileExists("public/sx/index.html", true)    // failing
	b.AssertFileExists("public/sx/p2/index.html", true) // failing
}

You can work around this by removing the cascade from matter, and specify the cascade in your site configuration instead:

[[cascade]]
[cascade.build]
render = 'never'
[cascade._target]
path = '{/s,/s/**}'

This will suppress rendering of all pages in the given section, including the section page itself.
