Excerpt breaks `&`?

Hi,

I use a model to customize the “title” of a page. Using a “excerpt” turns a & into a &.
Is this an expected behavior?

model.php

public function title(): Kirby\Content\Field
{
    return $this->headline()->excerpt(50)->or('podcast');
}

headline:

Hirn & Heinrich - der Wissenspodcast des Deutschen Zentrums für Neurodegenerative Erkrankungen e.V. (DZNE)

Result:

Hirn & Heinrich - der Wissenspodcast des …
     ^^^^^

How to keep the & as it is?

Thanks and have a nice day.

ciao, Stefan
