I have a few code blocks inside lists in my [“Importing from phpBB3” topic](https://meta.discourse.org/t/importing-from-phpbb3/30810/1). They looked fine when I posted this a few days ago. But now, after a small edit with insignificant changes, the line breaks inside the code blocks are gone.
The preview still looks fine:
The actual post however looks wrong:
Is this a regression or is there something wrong with my post?

Something’s wrong here. Will have a look.

Has already been reported. You need a blank line above or that will happen.
You also really ought to use 4 space indent rather than fenced code blocks when you don’t need syntax highlighting.

The strange thing is, it worked when I posted it two weeks ago…

Could be related to @sam’s changes to hack in `` support, don’t know.

Ok, I changed the way I format the code blocks for now. The thing is, I kinda like the bash syntax highlighting. 😉

The issue here really is why is the preview different than the cooked post?

I have a hunch on this.
We never _correctly_
```plaintext
hoisted
code blocks
```
and this incorrect hoisting, though not impacting the client that uses ember initializers to initialize dialects, did heavily impact the server that uses a different paradigm.
I fixed hoisting and unhoisting… but our architecture needs some TLC here, we need to split off the rendering engine into a cleaner, independent, multisite friendly piece.
