Wrapping Markdown source lines and empty lines as paragraph separators

I am a programmer and I am used to write Markdown with a maximum length of 80. The Helix editor can reflow paragraphs, so I don’t waste time with breaking lines. So I switch between editing in Obsidian and in Helix.

However line breaks are handled differently between Obsidian and Helix. A Markdown paragraph is one long line in Obsidian. In Helix I have an empty line separating paragraphs.

I prefer the way Helix handles Markdown. How can I configure Obsidian to automatically wrap lines after 80 columns and only treat empty lines as paragraph separators?

Thank you.
