fix: remove excess div wrappers (#4528)

* Removing superfluous div wrapping

It seems like standalone text is already wrapped in paragraph elements, so this code seems superfluous. Additionally, it adds div wrappers at every line break as described in #4524

* Fix for newlines and returns

This change skips newlines and returns to focus on unbounded text only.

* misc: fix indentation

* misc: fix indentation (2)
