Markdown Preview Not Respecting Line Breaks

[mdrockwell]

Expected

When previewing a note, text separated by a single line break should be displayed on separate lines.

When previewing a note, text separated by a single line break is displayed on the same line.

Reproduced

1. Create a new note with markdown enabled.
2. Add text to the note with a single line break.
3. Switch to preview.

I think this is expected from official Markdown site:

The implication of the “one or more consecutive lines of text” rule is that Markdown supports “hard-wrapped” text paragraphs. This differs significantly from most other text-to-HTML formatters (including Movable Type’s “Convert Line Breaks” option) which translate every line break character in a paragraph into a
tag.

Please note this behaviour is sometimes changed by some markdown flavours or renderers

Here sample code:

Writing some text
On multiple lines ends up rendering a
Single line

Though, you can break a line with multiple 

Line breaks

Which would give :

Writing some text On multiple lines ends up rendering a Single line

Line breaks
