Setting for hard/soft line breaks

Thank you very much for this nice previewer!

**Is your feature request related to a problem? Please describe.**
I use for writing a max line width of 80 characters. The preview renders my line breaks, but I would like it to ignore them. For example,

these are
two lines

I would expect to be rendered into a single line (if the html window is wide enough).

**Describe the solution you'd like**
A setting would be nice to choose the behavior of the preview, perhaps.

**Describe alternatives you've considered**
I tried to look for customization or `eaf-markdown-*` vars, but couldn't find any.
