Bug summary

I have upgrade my bolt project from 4.2.5 to 5.1.24 and I got a behaviour which does not exist before. I have tested with a fresh install and I get the same behaviour.

With this value, the prefix or postfix are not display :

prefix: |
                <p>A text-only version of the content, that can be used to "tease"
                the content when it's used in listing pages or search results.</p>

With a line break or any character, this value, the prefix or postfix are display :

postfix: |
                
                <p>A text-only version of the content, that can be used to "tease"
                the content when it's used in listing pages or search results.</p>
