Incorrect breadcrumbs in local search

[FlorianKoerner]

Describe the bug

I don't even know what exactly is happening here, but the breadcrumbs in the local search are not correct here.

Reproduction

Create example page and search for Foo.

## Foo

Hello world

#### Bar

Hello world

## Baz

Hello world

Expected behavior

Breadcrumbs should only show titles of the own hierarchy.

Yeah, we are aware of this too. Working on fixes. Those links are wrong too, and they might be repeated. Happening only with nested headings.
