I appreciate the CSS solution, but I’d argue this is still a bug from a usability standpoint.
If in edit mode I type
> Here is some text in a blockquote
>
> Here is more text in a blockquote
I would expect that to appear in preview mode as
(screenshote from commonmark.org)
But Obsidian preview mode still leaves that newline out. I’m fine to use the CSS fix, but I’d suggest this is not commonly expected behavior and would be an easy fix to meet the standard. Thanks for considering!
